                               COMPANY DESCRIPTION


        CardioGenesis Corporation (formerly known as Eclipse Surgical
Technologies, Inc.), incorporated in California in 1989, designs, develops,
manufactures and distributes laser-based surgical products and disposable
fiber-optic accessories for the treatment of advanced cardiovascular disease.
Cardiovascular disease is the leading cause of death and disability in the U.S.
according to the American Heart Association. Coronary artery disease is the
principal form of cardiovascular disease and is characterized by a progressive
narrowing of the coronary arteries which supply blood to the heart. This
narrowing process is usually due to atherosclerosis, which is the buildup of
fatty deposits, or plaque, on the inner lining of the arteries. Coronary artery
disease reduces the available supply of oxygenated blood to the heart muscle,
potentially resulting in severe chest pain known as angina, as well as damage to
the heart. Typically, the condition worsens over time and often leads to heart
attack and/or death.

        Based on the Canadian Heart Association standards, a patient's severe
chest pain or angina is typically classified into four classes, ranging from
Class 1, in which angina pain results only from strenuous exertion, to the most
severe class, Class 4, in which the patient is unable to conduct any physical
activity without angina and angina may be present even at rest. The American
Heart Association estimates that more than six million Americans experience
angina symptoms.

        The primary therapeutic options for treatment of coronary artery disease
are drug therapy, balloon angioplasty, other interventional techniques which
augment or replace balloon angioplasty such as stent placement, and coronary
artery bypass grafting which is more commonly referred to as bypass. The
objective of each of these approaches is to increase blood flow through the
coronary arteries to the heart.

        Drug therapy may be effective for mild cases of coronary artery disease
and angina either through medical effects on the arteries that improve blood
flow without reducing the fatty deposits which line the coronary arteries or by
decreasing the rate of formation of additional fatty deposits by reducing blood
levels of cholesterol. Because of the progressive nature of the disease,
however, many patients with angina ultimately undergo either balloon angioplasty
or bypass.

        When these treatment options are exhausted, the patient is left with no
viable surgical or interventional alternative other than, in limited cases,
heart transplantation. Without a viable surgical alternative, the patient is
generally managed with drug therapy, often with significant lifestyle
limitations.



                                       3

        The laser-based surgical products designed, developed, manufactured and
distributed by CardioGenesis Corporation are used for the treatment of advanced
cardiovascular disease through two procedures, transmyocardial revascularization
known as TMR and percutaneous transluminal myocardial revascularization known as
PTMR. TMR and PTMR are recent laser-based heart treatments in which channels are
made in the heart muscle. It is believed that the TMR and PTMR procedures
encourage new blood vessel formation in the heart region known as angiogenesis.
Clinical studies have demonstrated a significant reduction in angina and an
increase in exercise duration in patients treated with TMR and PTMR plus
medications when compared with patients who received medications alone.

        We distribute a laser system, called the TMR laser system, which is used
in the TMR surgical procedure. TMR, or transmyocardial revascularization, is a
surgical procedure performed by a cardiac surgeon on the beating or non-beating
heart, in which a laser device is used to create channels through the
myocardium, i.e. heart muscle, directly into the heart chamber. The channels are
intended to supply blood to oxygen-deprived, or ischemic, regions of the
myocardium and reduce angina in the patient. TMR can be performed using open
chest surgery or minimally invasive surgery through a small incision between the
ribs. TMR offers cardiac patients suffering from severe angina who have regions
in the heart that are oxygen-deprived but cannot be treated by balloon
angioplasty or bypass.

        On February 11, 1999, we received final approval from the Food and Drug
Administration for our TMR products for the treatment of a specific type of
patient suffering from severe coronary artery disease. The precise approval
granted by the Food and Drug Administration, in medical terminology, states that
"the TMR product is approved for treatment of stable Canadian Cardiovascular
Society class 4 patients with angina refractory to other medical treatments and
secondary to objectively demonstrated coronary artery atherosclerosis and with a
region of the myocardium with reversible ischemia not amenable to direct
coronary revascularization." As of July 1, 1999, the Health Care Financial
Administration began to provide Medicare coverage for TMR. Hospitals and
physicians are now eligible to receive Medicare reimbursement for the full costs
of TMR equipment and procedures.

        PTMR, or percutaneous transluminal myocardial revascularization, is an
interventional procedure performed by a cardiologist. PTMR is based upon the
same principles as TMR, but the procedure is much less invasive. PTMR is not
performed using open chest surgery (which is invasive), rather, the patient is
under local anesthesia and is treated through a catheter inserted in the femoral
artery at the top of the leg. From the femoral artery, a laser transmitting
catheter is threaded up into the heart chamber, where channels are created in
the inner portion of the myocardium (i.e. heart muscle).

        We distribute a laser system, called the PTMR laser system, which is
used in the PTMR procedure. In the United States, we offered our PTMR laser
systems for sale in limited numbers for investigational use only pursuant to
Investigational Device Exemptions from the United States Food and Drug
Administration. We have completed pivotal clinical trials involving PTMR, and
study results were submitted to the Food and Drug Administration in a Pre Market
Approval application in December of 1999. There can be no assurance, however,
that we will receive a favorable decision from that agency. We are scheduled for
a panel meeting with the Food and Drug Administration Advisory Panel on July 9,
2001 at which the Panel is expected to issue either a favorable or unfavorable
recommendation to the Food and Drug Administration.



        Our principal executive offices are located at 26632 Towne Center Drive,
Suite 260, Foothill Ranch, California 92610. Our telephone number is (949)
859-4031.


                                  RISK FACTORS




        Before you invest in our common stock, you should be aware of the
various risks and uncertainties associated with such an investment, including
those described below. You should consider carefully these risk factors together
with all of the other information included in this prospectus and in the
documents incorporated by reference before you decide to purchase our common
stock.

WE MAY REQUIRE ADDITIONAL FUNDS FOR OPERATING EXPENSES AND IF WE ARE NOT ABLE
TO SECURE ADDITIONAL FINANCING IN THE FUTURE, OUR BUSINESS WILL SUFFER.



        In the future, we may require additional funds for operating expenses.
We may be required to seek additional sources of financing, which could include
short-term debt, long-term debt or equity. There is a risk that we may be
unsuccessful in obtaining such financing and will not have sufficient cash to
fund our operations. If this occurs, we may have to significantly reduce our
operations until an appropriate solution is implemented.

WE MAY FAIL TO OBTAIN REQUIRED REGULATORY APPROVALS TO MARKET OUR PRODUCTS
INCLUDING OUR PTMR LASER SYSTEM IN THE UNITED STATES.



        Our business could be harmed if any of the following events,
circumstances or occurrences related to the regulatory process occurred thereby
causing a reduction in our revenues:


        -   the failure to obtain regulatory approvals for our PTMR system;

        -   significant limitations in the indicated uses for which our products
            may be marketed;

        -   substantial costs incurred in obtaining regulatory approvals.





        The Food and Drug Administration has not approved our PTMR laser systems
for any indication in the United States. The PTMR study compares PTMR to
conventional medical therapy in patients with no option for other treatment. The
Food and Drug Administration may not accept the study as safe and effective, and
PTMR may not be approved for commercial use in the United States. Responding to
Food and Drug Administration requests for additional information could require
substantial financial and management resources and take several years.

        In October 2000, preliminary results from a competitor's clinical trial
of a catheter-based device employing Direct Myocardial Revascularization also
known as DMR were presented at a medical conference in Washington D.C. The
trial's principal investigator concluded that this catheter-based device did not
show significant evidence of clinical benefit with regard to angina class
reduction or exercise tolerance, and questioned the efficacy of other devices
and procedures relying on TMR. We believe that the preliminary results of that
catheter-based device study should not call the results of our PTMR study into
question because the devices and procedures are substantially different. We
cannot assure you, however, that the preliminary results of that catheter-based
device study will impact the Food and Drug Administration's decision on our PTMR
system.


THE MEDICAL COMMUNITY HAS NOT BROADLY ADOPTED OUR PRODUCTS, AND UNLESS OUR
PRODUCTS ARE BROADLY ADOPTED, OUR BUSINESS WILL SUFFER.

        Our TMR products have not yet achieved broad commercial adoption, and
our PTMR products are experimental and have not yet achieved broad clinical
adoption. We cannot predict whether or at what rate and how broadly our products
will be adopted by the medical community. Our business would be harmed if our
TMR and PTMR systems fail to achieve significant market acceptance.


THE RECEIPT OF POSITIVE ENDORSEMENTS BY PHYSICIANS IS ESSENTIAL FOR THE SUCCESS
OF OUR PRODUCTS IN THE MARKET PLACE.



        Positive endorsements, by physicians, are essential for clinical
adoption of our TMR and PTMR laser systems. Even if the clinical efficacy of TMR
and PTMR laser systems is established, physicians may elect not to recommend TMR
and PTMR laser systems for any number of reasons.



                                       5
   6



        Clinical adoption of these products will depend upon:

        -   our ability to facilitate training of cardiothoracic surgeons and
            interventional cardiologists in TMR and PTMR therapy;

        -   willingness of such physicians to adopt and recommend such
            procedures to their patients; and

        -   raising the awareness of TMR and then PTMR with the targeted patient
            population.

        Patient acceptance of the procedure will depend on:

        -   physician recommendations;

        -   the degree of invasiveness;

        -   the effectiveness of the procedure; and

        -   the rate and severity of complications associated with the procedure
            as compared to other procedures.


TO EXPAND OUR BUSINESS, WE MUST ESTABLISH EFFECTIVE SALES, MARKETING AND
DISTRIBUTION SYSTEMS.



        To expand our business, we must establish effective systems to sell,
market and distribute products. To date, we have had limited sales which have
consisted primarily of U.S. sales of our TMR lasers and disposable handpieces on
a commercial basis since February 1999 and PTMR lasers and disposable catheters
for investigational use only. We have been expanding our operations by hiring
additional sales and marketing personnel. This has required and will continue to
require substantial management effort and financial resources.

IF OUR SALES FORCE IS NOT SUCCESSFUL IN INCREASING MARKET SHARE AND SELLING OUR
DISPOSABLE HANDPIECES, OUR BUSINESS WILL SUFFER.

        With Food and Drug Administration approval of our TMR laser system, we
are marketing our products primarily through our direct sales force. If the
sales force is not successful in increasing market share and selling our
disposable handpieces, our business will suffer. In the fourth quarter of 1999,
we changed our U.S. sales strategy to include both selling lasers to hospitals
outright, as well as loaning lasers to hospitals in return for the hospital
purchasing a minimum number of disposable handpieces at a higher price. During
the current year, the majority of lasers shipped have been under this loan
program. The purpose of this strategy is to focus our sales force on increasing
market penetration and selling disposable handpieces used in connection with our
TMR procedure.




THE EXPANSION OF OUR BUSINESS MAY PUT ADDED PRESSURE ON OUR MANAGEMENT AND
OPERATIONAL INFRASTRUCTURE AND COULD CREATE NUMEROUS RISKS AND CHALLENGES.


        The growth in our business may place a significant strain on our limited
personnel, management and other resources. The evolving growth of our business
presents numerous risks and challenges, including:


        -   the dependence on the growth of the market for our TMR and PTMR
            systems;

        -   domestic and international regulatory developments;

        -   rapid technological change;


                                       6
   7

        -   the highly competitive nature of the medical devices industry; and

        -   the risk of entering emerging markets in which we have limited or no
            direct experience.

        Our future operating results will be significantly affected by our
ability to:

        -   successfully and rapidly expand sales to potential customers;

        -   implement operating, manufacturing and financial procedures and
            controls;

        -   improve coordination among different operating functions;

        -   continue to attract, train and motivate additional qualified
            personnel in all areas; and

        -   achieve manufacturing efficiencies as production volume increases.


        If we are not able to manage these activities and implement these
strategies successfully, our operating results could suffer.

OUR OPERATING RESULTS ARE EXPECTED TO FLUCTUATE AND QUARTER-TO-QUARTER
COMPARISONS OF OUR RESULTS MAY NOT INDICATE FUTURE PERFORMANCE.



        Our operating results have fluctuated significantly from
quarter-to-quarter and are expected to fluctuate significantly from
quarter-to-quarter due to a number of events and factors, including:


        -   the level of product demand and the timing of customer orders;

        -   changes in strategy;


        -   delays associated with the Food and Drug Administration and other
            regulatory approval processes;


        -   personnel changes;

        -   the level of international sales;

        -   changes in competitive pricing policies;

        -   the ability to develop, introduce and market new and enhanced
            versions of products on a timely basis;

        -   deferrals in customer orders in anticipation of new or enhanced
            products;

        -   product quality problems; and

        -   the enactment of health care reform legislation and any changes in
            third party reimbursement policies.


        We believe that quarter-to-quarter comparisons of our operating results
are not a good indication of our future performance. Due to the emerging nature
of the markets in which we compete, forecasting operating results is difficult
and unreliable. Over the past year, our revenue has been lower than anticipated,
largely attributable to the transition to our new sales strategy. It is likely
or possible that our operating results for a future quarter will fall below the
expectations of public market analysts and investors. When this occurred in the
past, the price of our common stock fell substantially, and if this occurs
again, the price of our common stock may fall again, perhaps substantially.





WE MAY NOT BE ABLE TO SUCCESSFULLY MARKET OUR PRODUCTS IF THIRD PARTY
REIMBURSEMENT FOR THE PROCEDURES PERFORMED WITH OUR PRODUCTS IS NOT AVAILABLE
FOR OUR HEALTH CARE PROVIDER CUSTOMERS.


        Few individuals are able to pay directly for the costs associated with
the use of our products. In the United States, hospitals, physicians and other
healthcare providers that purchase medical devices generally rely on third party
payors, such as Medicare, to reimburse all or part of the cost of the procedure
in which the medical device is being used.



                                       7
   8





        Effective July 1, 1999, the Health Care Financing Administration
commenced Medicare coverage for TMR systems for any manufacturer's TMR
procedures. Hospitals and physicians are now eligible to receive Medicare
reimbursement covering 100% of the costs for TMR procedures and equipment. The
Health Care Financing Administration may not approve reimbursement for PTMR. If
it does not provide reimbursement, our ability to successfully market and sell
our PTMR products will be harmed. We have limited experience to date with the
acceptability of our TMR procedures for reimbursement by private insurance and
private health plans and thus do not have reliable data as to the success of our
patients in obtaining reimbursement for the costs of our TMR products outside of
the Medicare system. Private insurance and private health plans may not approve
reimbursement TMR or PTMR procedures. If they do not provide reimbursement, our
business will suffer.




        Potential purchasers must determine whether the clinical benefits of our
TMR and PTMR laser systems justify:

        -   the additional cost or the additional effort required to obtain
            prior authorization or coverage; and

        -   the uncertainty of actually obtaining such authorization or
            coverage.


WE FACE COMPETITION FROM OUR COMPETITOR'S PRODUCTS WHICH COULD LIMIT
MARKET ACCEPTANCE OF OUR PRODUCTS AND RENDER OUR PRODUCTS OBSOLETE.



        The market for TMR laser systems is competitive. If our competitor is
more effective in developing new products and procedures and marketing existing
and future products, our business will suffer. The market for TMR laser systems
is characterized by rapid technical innovation. Accordingly, our current or
future competitors may succeed in developing TMR products or procedures that:


        -   are more effective than our products;

        -   are more effectively marketed than our products; or

        -   may render our products or technology obsolete.


        We currently compete with PLC Systems, Inc. PLC is currently selling TMR
commercially in the United States and abroad. PLC recently announced a
co-marketing agreement with Edwards Life Sciences to distribute their lasers and
disposables which is expected to add another 18 direct domestic sales
representatives involved in promoting the PLC technology.



        Even with the Food and Drug Administration approval for our TMR laser
system, we will face competition for market acceptance and market share for that
product. Our ability to compete may depend in significant part on the timing of
introduction of competitive products into the market, and will be affected by
the pace, relative to competitors, at which we are able to:


        -   develop products;

                                       8

   9

        -   complete clinical testing and regulatory approval processes;

        -   obtain third party reimbursement acceptance; and

        -   supply adequate quantities of the product to the market.




OUR PRODUCTS DEPEND ON TMR TECHNOLOGY THAT IS RAPIDLY CHANGING WHICH MAY REQUIRE
US TO INCUR SUBSTANTIAL PRODUCT DEVELOPMENT EXPENDITURES TO PREVENT OUR PRODUCTS
FROM BECOMING OBSOLETE.






        The medical device industry is characterized by rapid and significant
technological change. Our future success will depend in large part on our
ability to respond to such changes through further product research and
development. In addition, we must expand the indications and applications for
our products by developing and introducing enhanced and new versions of our TMR
and PTMR laser systems. Product research and development requires substantial
expenditures and is inherently risky. We may not be able to:


        -   identify products for which demand exists; or

        -   develop products that have the characteristics necessary to treat
            particular indications.



OVERALL INCREASES IN MEDICAL COSTS COULD ADVERSELY AFFECT OUR BUSINESS.


        We believe that the overall escalating cost of medical products and
services has led, and will continue to lead, to increased pressures on the
health care industry, both foreign and domestic, to reduce the cost of products
and services, including products offered by them. We cannot assure you that in
either United States or international markets that:


        -   third party reimbursement and coverage will be available or
            adequate;

        -   current reimbursement amounts will not be decreased in the future;
            or

        -   future legislation, regulation or reimbursement policies of third
            party payors will not otherwise adversely affect the demand for our
            products or our ability to profitably sell our products.

        Fundamental reforms in the healthcare industry in the United States and
Europe continue to be considered. We cannot predict whether or when any
healthcare reform proposals will be adopted and what effect such proposals might
have on our business.

WE HAVE A HISTORY OF LOSSES AND MAY NOT BE PROFITABLE IN THE FUTURE.

        We have incurred significant losses since inception. Our revenues and
operating income will be constrained:

        -   until such time, if ever, as we obtain broad commercial adoption of
            our TMR laser systems by healthcare facilities in the United States;


        -   until such time, if ever, as we obtain Food and Drug Administration
            and other regulatory approvals for our PTMR laser systems; and


        -   for an uncertain period of time after such approvals are obtained.

        We may not achieve or sustain profitability in the future.






OUR ABILITY TO CONTINUE AS A GOING CONCERN IS DEPENDENT UPON ACHIEVING
PROFITABLE OPERATIONS IN THE FUTURE.




        We will have a continuing need for new infusions of cash until revenues
are increased to meet our expenditures. We plan to increase our sales through
increased direct sales and marketing efforts on existing products and achieving
timely regulatory approval for other products under clinical trials. We believe
that if we are unable to generate sufficient funds from sales or from debt or
equity issuances to maintain our current expenditure rate, it will be necessary
to significantly reduce our operations. This would raise substantial doubt about
our ability to continue as a going concern.


                                       9

THIRD PARTIES MAY LIMIT THE DEVELOPMENT AND PROTECTION OF OUR INTELLECTUAL
PROPERTY, WHICH COULD ADVERSELY AFFECT OUR COMPETITIVE POSITION.

        Our success is dependent in large part on our ability to:

        -   obtain patent protection for our products and processes;

        -   preserve our trade secrets and proprietary technology; and

        -   operate without infringing upon the patents or proprietary rights of
            third parties.

        The medical device industry has been characterized by extensive
litigation regarding patents and other intellectual property rights. Companies
in the medical device industry have employed intellectual property litigation to
gain a competitive advantage. Certain competitors and potential competitors of
ours have obtained United States patents covering technology that could be used
for certain TMR and PTMR procedures. We do not know if such competitors,
potential competitors or others have filed and hold international patents
covering other TMR or PTMR technology. In addition, international patents may
not be interpreted the same as any counterpart United States patents.

        In September 1995, one of our competitors sent us a notice of potential
infringement of their patent regarding a method for TMR utilizing
synchronization of laser pulses to the electrical signals from the heart. After
discussion with patent counsel, we concluded that we did not utilize the process
and/or apparatus that was the subject of the patent at issue, and we provided a
response to the competitor to that effect. We have not received any additional
correspondence from this competitor on these matters.


        In 1996, prior to the merger with us, the company formerly known as
CardioGenesis initiated a suit in the United States against PLC seeking a
judgment that the PLC patent is invalid and unenforceable. In 1997, PLC
counterclaimed in that suit alleging infringement by CardioGenesis of the PLC
patent. Also in 1997, PLC initiated suit in Germany against CardioGenesis and
CardioGenesis' former German sales agent alleging infringement of a European
counterpart to the PLC patent. In 1997, CardioGenesis filed an Opposition in the
European Patent Office to a European counterpart to the PLC patent, seeking to
have the European patent declared invalid.

        On January 5, 1999, before trial on the United States suit commenced,
the company formerly known as CardioGenesis and PLC settled all litigation
between them, both in the United States and in Germany, with respect to the PLC
patent and the European patents. Under the Settlement and License Agreement
signed by the parties, CardioGenesis stipulated to the validity of the PLC
patents and PLC granted CardioGenesis a non-exclusive worldwide license to the
PLC patents. CardioGenesis agreed to pay PLC a license fee, and minimum
royalties, totaling $2.5 million in equal monthly installments over an
approximately forty-month period, with a running royalty credited against the
minimums.

        The Settlement and License Agreement applies only to those products or
that technology covered by the PLC patents, and the agreement does not provide
PLC any rights to any CardioGenesis intellectual property. Our TMR 2000 laser
system does not use the technology associated with the PLC patents.


        While we periodically review the scope of our patents and other relevant
patents of which we are aware, the question of patent infringement involves
complex legal and factual issues. Any conclusion regarding infringement may not
be consistent with the resolution of any such issues by a court.



COSTLY LITIGATION MAY BE NECESSARY TO PROTECT INTELLECTUAL PROPERTY RIGHTS.

        We may have to engage in time consuming and costly litigation to protect
our intellectual property rights or to determine the proprietary rights of
others. In addition, we may become subject to patent infringement claims or
litigation, or interference proceedings declared by the United States Patent and
Trademark Office to determine the priority of inventions.


                                       10
   11

        Defending and prosecuting intellectual property suits, United States
Patent and Trademark Office interference proceedings and related legal and
administrative proceedings are both costly and time-consuming. We may be
required to litigate further to:

        -   enforce our issued patents;

        -   protect our trade secrets or know-how; or

        -   determine the enforceability, scope and validity of the proprietary
            rights of others.

        Any litigation or interference proceedings will result in substantial
expense and significant diversion of effort by technical and management
personnel. If the results of such litigation or interference proceedings are
adverse to us, then the results may:

        -   subject us to significant liabilities to third parties;

        -   require us to seek licenses from third parties;

        -   prevent us from selling our products in certain markets or at all;
            or

        -   require us to modify our products.

        Although patent and intellectual property disputes regarding medical
devices are often settled through licensing and similar arrangements, costs
associated with such arrangements may be substantial and could include ongoing
royalties. Furthermore, we may not be able to obtain the necessary licenses on
satisfactory terms, if at all.

        Adverse determinations in a judicial or administrative proceeding or
failure to obtain necessary licenses could prevent us from manufacturing and
selling our products. This would harm our business.


        The United States patent laws exempt physicians, other health care
professionals, and affiliated entities from infringement liability for medical
and surgical procedures performed on patients. We are not able to predict if
this amendment will materially affect our ability to protect our proprietary
methods and procedures.


WE RELY ON PATENT AND TRADE SECRET LAWS, WHICH ARE COMPLEX AND MAY BE DIFFICULT
TO ENFORCE.

        The validity and breadth of claims in medical technology patents involve
complex legal and factual questions and, therefore, may be highly uncertain.
Issued patent or patents based on pending patent applications or any future
patent application may not exclude competitors or may not provide a competitive
advantage to us. In addition, patents issued or licensed to us may not be held
valid if subsequently challenged and others may claim rights in or ownership of
such patents.

        Furthermore, we cannot assure you that our competitors:

        -   have not developed or will not develop similar products;

        -   will not duplicate our products; or

        -   will not design around any patents issued to or licensed by us.

        Because patent applications in the United States were, until recently,
maintained in secrecy until patents issue, we cannot be certain that:

        -   others did not first file applications for inventions covered by our
            pending patent applications; or

        -   we will not infringe any patents that may issue to others on such
            applications.





IF WE EXPERIENCE INCREASED DEMAND FOR OUR PRODUCTS, WE MAY NOT BE ABLE TO EXPAND
OUR BUSINESS TO MEET SUCH DEMAND.

        We may be required to expand our business to:



                                       11
   12


        -   respond to increasing clinical adoption of the TMR procedure;

        -   respond to successful sales and marketing efforts of the TMR
            product;

        -   develop future products;

        -   generally compete successfully;

        -   complete the clinical trials that are currently in progress; and

        -   prepare additional products for clinical trials.




        Such expansion, which could possibly occur within the next 24 months,
could place a significant strain on managerial, operational and financial
systems and resources. In addition, the cost to expand such resources is
difficult to quantify but could be significant. To accommodate such expansion
and compete effectively, we must obtain additional funding to improve
information systems, procedures and controls and expand, train, motivate and
manage our employees, and such funding may not be available in sufficient
quantities, if at all.


WE DEPEND ON SINGLE SOURCE SUPPLIERS FOR KEY COMPONENTS AND PRODUCTION WOULD BE
INTERRUPTED IF A KEY SUPPLIER HAD TO BE REPLACED.


        We currently purchase critical laser and fiber-optic components from
single sources. These sources may have difficulties supplying our needs for
these components. In addition, we do not have long term supply contracts. As a
result, these sources are not obligated to continue to provide these critical
components to us. Although we have identified alternative suppliers, a lengthy
process would be required to qualify them as additional or replacement
suppliers. Any significant interruption in the supply of critical materials or
components could delay our ability to manufacture our products and could disrupt
our manufacturing operations and harm our business.

LEAD TIMES FOR MATERIALS AND COMPONENTS VARY SIGNIFICANTLY WHICH COULD LEAD TO
EXCESS INVENTORY LEVELS AS WELL AS SHORTAGES OF CRITICAL COMPONENTS IF OUR
SUPPLY FORECASTS ARE INACCURATE.


        We anticipate that products will be manufactured based on forecasted
demand and will seek to purchase subassemblies and components in anticipation of
the actual receipt of purchase orders from customers. Lead times for materials
and components vary significantly and depend on factors such as the business
practices of each specific supplier and the terms of particular contracts, as
well as the overall market demand for such materials and components at any given
time. If the forecasts are inaccurate, we could experience fluctuations in
inventory levels, resulting in excess inventory, or shortages of critical
components, either of which could cause our business to suffer.


WE MAY NOT BE ABLE TO MEET FUTURE DEMAND INCREASES ON TIMELY BASIS BECAUSE SOME
OF OUR SUPPLIERS COULD HAVE DIFFICULTY MEETING SIGNIFICANT OR RAPIDLY INCREASING
ORDER AMOUNTS.

        Some of our suppliers could have difficulty expanding their
manufacturing capacity to meet our needs if demand for our TMR and PTMR laser
systems were to increase rapidly or significantly. In addition, any defect or
malfunction in the laser or other products provided by such suppliers could
cause a delay in regulatory approvals or adversely affect product acceptance. We
cannot predict if:
        -   materials obtained from outside suppliers will be available in
            adequate quantities to meet our future needs; or

        -   replacement suppliers can be qualified on a timely basis if our
            current suppliers are unable to meet our needs.

WE HAVE LIMITED MANUFACTURING EXPERIENCE WHICH COULD PREVENT US FROM
SUCCESSFULLY INCREASING CAPACITY IN RESPONSE TO MARKET DEMAND.

        We have limited experience in manufacturing products. In the course of
manufacturing our products, we may encounter difficulties in increasing
production, including problems involving:


        -   production yields;



                                       12
   13

        -   adequate supplies of components;

        -   quality control and assurance (including failure to comply with good
            manufacturing practices regulations, international quality standards
            and other regulatory requirements); and

        -   shortages of qualified personnel.



OUR PRODUCTS MAY CONTAIN DEFECTS WHICH COULD DELAY REGULATORY APPROVAL OR MARKET
ACCEPTANCE OF OUR PRODUCTS.


        We may experience future product defects, malfunctions, manufacturing
difficulties or recalls related to the lasers or other components used in our
TMR and PTMR laser systems. Any such occurrence could cause a delay in
regulatory approvals or adversely affect the commercial acceptance of our
products. We are unable to quantify the likelihood or costs of any such
occurrences, but they could potentially be significant. Our business could be
harmed because we may be unable to sufficiently remedy a significant product
recall while still maintaining our daily manufacturing quotas.

WE MUST COMPLY WITH FOOD AND DRUG ADMINISTRATION MANUFACTURING STANDARDS OR FACE
FINES OR OTHER PENALTIES INCLUDING SUSPENSION OF PRODUCTION.

        We are required to demonstrate compliance with the Food and Drug
Administration's current good manufacturing practices regulations if we market
devices in the United States or manufacture finished devices in the United
States. The Food and Drug Administration inspects manufacturing facilities on a
regular basis to determine compliance. If we fail to comply with applicable Food
and Drug Administration or other regulatory requirements, we can be subject to:


        -   fines, injunctions, and civil penalties;

        -   recalls or seizures of products;

        -   total or partial suspensions of production; and

        -   criminal prosecutions.


        The impact on the company of any such failure to comply would depend on
the impact of the remedy imposed on us.


WE MAY SUFFER LOSSES FROM PRODUCT LIABILITY CLAIMS IF OUR PRODUCTS CAUSE HARM TO
PATIENTS.

        We are exposed to potential product liability claims and product
recalls. These risks are inherent in the design, development, manufacture and
marketing of medical devices. Our products are designed to be used in
life-threatening situations where there is a high risk of serious injury or
death, and we could be subject to product liability claims if the use of our TMR
or PTMR laser systems is alleged to have caused adverse effects on a patient or
such products are believed to be defective.


        Any regulatory clearance for commercial sale of these products will not
remove these risks. Any failure to comply with the Food and Drug
Administration's good manufacturing practices or other regulations could hurt
our ability to defend against product liability lawsuits. Although we have not
experienced any product liability claims to date, any such claims could cause
our business to suffer.


OUR INSURANCE MAY BE INSUFFICIENT TO COVER PRODUCT LIABILITY CLAIMS AGAINST US.

        Our product liability insurance may not be adequate for any future
product liability problems or continue to be available on commercially
reasonable terms, or at all.

        If we were held liable for a product liability claim or series of claims
in excess of our insurance coverage, such liability could harm our business and
financial condition. We maintain insurance against product liability claims in
the amount of $10 million per occurrence and $10 million in the aggregate.


                                       13
   14

        We may require increased product liability coverage as sales of approved
products increase and as additional products are commercialized. Product
liability insurance is expensive and in the future may not be available on
acceptable terms, if at all.


WE DEPEND HEAVILY ON KEY PERSONNEL AND TURNOVER OF KEY EMPLOYEES AND SENIOR
MANAGEMENT COULD HARM OUR BUSINESS.

        Our future business and results of operations depend in significant part
upon the continued contributions of our key technical and senior management
personnel. They also depend in significant part upon our ability to attract and
retain additional qualified management, manufacturing, technical, marketing and
sales and support personnel for our operations. If we lose a key employee or if
a key employee fails to perform in his or her current position, or if we are not
able to attract and retain skilled employees as needed, our business could
suffer.

        During the last two years, we have had significant change in our senior
management team. Our former Chief Executive Officer, Allen Hill, resigned from
the company in December 1999. One of our current Directors, Alan Kaganov, acted
as interim CEO until we hired our current CEO, Michael Quinn, in October of
2000. Our former Chief Financial Officer, Dick Powers, resigned from the company
in July 2000. Ian Johnson acted as Interim CFO until our current CFO, J. Stephen
Wilkins, was hired in May 2001. Richard Lanigan moved from Vice President of
Sales to Vice President of Regulatory and Government Affairs in March 2001 and
Thomas Kinder was hired in March 2001 as our new Vice President of Sales.
Darrell Eckstein was hired in December 2000 as our Vice President of Operations,
replacing Bill Picht, who resigned earlier in 2000.

        Our future business could be harmed by our turnover in senior management
if we have difficulty familiarizing and training our new management with respect
to our business. Further significant turnover in our senior management could
significantly deplete our institutional knowledge held by our existing senior
management team. We depend on the skills and abilities of these key employees in
managing the manufacturing, technical, marketing and sales aspects of our
business, any part of which could be harmed by further turnover.


WE MAY FAIL TO COMPLY WITH INTERNATIONAL REGULATORY REQUIREMENTS AND COULD BE
SUBJECT TO REGULATORY DELAYS, FINES OR OTHER PENALTIES.


        Regulatory requirements in foreign countries for international sales of
medical devices often vary from country to country. In addition, the Food and
Drug Administration must approve the export of devices to certain countries. The
occurrence and related impact of the following factors would harm our business:


        -   delays in receipt of, or failure to receive, foreign regulatory
            approvals or clearances;

        -   the loss of previously obtained approvals or clearances; or

        -   the failure to comply with existing or future regulatory
            requirements.


        To market in Europe, a manufacturer must obtain the certifications
necessary to affix to its products the CE Marking. The CE Marking is an
international symbol of adherence to quality assurance standards and compliance
with applicable European medical device directives. In order to obtain and to
maintain a CE Marking, a manufacturer must be in compliance with the appropriate
quality assurance provisions of the International Standards Organization and
obtain certification of its quality assurance systems by a recognized European
Union notified body. However, certain individual countries within Europe require
further approval by their national regulatory agencies.

        We have achieved International Standards Organization and European Union
certification for our manufacturing facility. In addition, we have completed CE
mark registration for all of our products in accordance with the implementation
of various medical device directives in the European Union. Failure to maintain
the right to affix the CE Marking or other requisite approvals could prohibit us
from selling our TMR products in member countries of the European Union or
elsewhere. Any enforcement action by international regulatory authorities with
respect to past or future regulatory noncompliance could cause our business to
suffer. Noncompliance with international regulatory requirements could result in
enforcement action such as not being allowed to market our product in the
European Union, which would significantly reduce international revenue.




                                       14
   15






WE SELL OUR PRODUCTS INTERNATIONALLY WHICH SUBJECTS US TO SPECIFIC RISKS OF
TRANSACTING BUSINESS IN FOREIGN COUNTRIES.

        In future quarters, international sales may become a significant portion
of our revenue if our products become more widely used outside of the United
States according to our plan. Our international revenue is subject to the
following risks, the occurrence of any of which could harm our business:


        -   foreign currency fluctuations;

        -   economic or political instability;

        -   foreign tax laws;

        -   shipping delays;

        -   various tariffs and trade regulations;

        -   restrictions and foreign medical regulations;

        -   customs duties, export quotas or other trade restrictions; and

        -   difficulty in protecting intellectual property rights.



WE MAY NOT ACHIEVE WIDE ACCEPTANCE OF OUR PRODUCTS IN FOREIGN MARKETS IF WE FAIL
TO OBTAIN THIRD PARTY REIMBURSEMENT FOR THE PROCEDURES PERFORMED WITH OUR
PRODUCTS.


        If we obtain the necessary foreign regulatory registrations or
approvals, market acceptance of our products in international markets would be
dependent, in part, upon the availability of reimbursement within prevailing
health care payment systems. Reimbursement is a significant factor considered by
hospitals in determining whether to acquire new equipment. A hospital is more
inclined to purchase new equipment if third-party reimbursement can be obtained.
Reimbursement and health care payment systems in international markets vary
significantly by country. They include both government sponsored health care and
private insurance. Although we expect to seek international reimbursement
approvals, any such approvals may not be obtained in a timely manner, if at all.
Failure to receive international reimbursement approvals could hurt market
acceptance of TMR products in the international markets in which such approvals
are sought, which would significantly reduce international revenue.

WE MAY ENGAGE IN FUTURE ACQUISITIONS THAT COULD DISTRACT OUR MANAGEMENT, CAUSE
US TO INCUR DEBT, OR DILUTE OUR SHAREHOLDERS.

        We may, from time to time, acquire or invest in other complementary
businesses, products or technologies. While there are currently no commitments
with respect to any particular acquisition or investment, our management
frequently evaluates the strategic opportunities available in complementary
businesses, products or technologies. The process of integrating an acquired
company's business into our operations may result in unforeseen operating
difficulties and expenditures and may absorb significant management attention
that would otherwise be available for the ongoing development of our business.
Moreover, the anticipated benefits of any acquisition or investment may not be
realized. Any future acquisitions or investments by us could result in
potentially dilutive issuances of equity securities, the incurrence of debt and
contingent liabilities and amortization expenses related to goodwill and other
intangible assets, any of which could materially harm our operating results.


THE PRICE OF OUR COMMON STOCK MAY FLUCTUATE SIGNIFICANTLY, WHICH MAY RESULT IN
LOSSES FOR INVESTORS.


        The market price for our common stock has been and may continue to be
volatile. For example, during the 52-week period ended June 25, 2001, the
closing prices of our common stock as reported on the NASDAQ National Market
ranged from a high of $4.75 to a low of $0.50. We expect our stock price to be
subject to fluctuations as a result of a variety of factors, including factors
beyond our control. These factors include:


        -   actual or anticipated variations in our quarterly operating results;

        -   announcements of technological innovations or new products or
            services by us or our competitors;


                                       15
   16

        -   announcements relating to strategic relationships or acquisitions;

        -   changes in financial estimates by securities analysts;

        -   statements by securities analysts regarding us or our industry;

        -   conditions or trends in the medical device industry; and

        -   changes in the economic performance and/or market valuations of
            other medical device companies.

        Because of this volatility, we may fail to meet the expectations of our
shareholders or of securities analysts at some time in the future, and our stock
price could decline as a result.

        In addition, the stock market has experienced significant price and
volume fluctuations that have particularly affected the trading prices of equity
securities of many high technology companies. These fluctuations have often been
unrelated or disproportionate to the operating performance of these companies.
Any negative change in the public's perception of medical device companies could
depress our stock price regardless of our operating results. If our common stock
were to trade under $1.00 for 30 consecutive days on the NASDAQ National Market,
our common stock could be subject to certain consequences established by the
NASDAQ National Market such as being delisted.

        Recently, when the market price of a stock has been volatile, holders of
that stock have often instituted securities class action litigation against the
company that issued the stock. If any of our shareholders brought such a lawsuit
against us, we could incur substantial costs defending the lawsuit. The lawsuit
could also divert the time and attention of our management.

                           FORWARD-LOOKING INFORMATION

        This prospectus contains or incorporates by reference forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended,
that involve risks and uncertainties. Forward-looking statements can typically
be identified by the use of forward-looking words, such as "may," "will,"
"could," "project," "believe," anticipate," "expect," "estimate," "continue,"
"potential," "plan," "forecasts," and the like. These statements appear in a
number of places in this prospectus and include statements regarding our
intentions, plans, strategies, beliefs or current expectations and those of our
directors or our officers with respect to, among other things:

               -      our financial prospects;

               -      our financing plans;

               -      trends affecting our financial condition or operating
                      results; and

               -      our strategies for growth, operations, and product
                      development and commercialization.

        Forward-looking statements do not guarantee future performance and
involve risks and uncertainties that could cause actual results to differ
materially from those anticipated. The information contained in this prospectus,
or incorporated by reference, identifies important factors that could cause such
differences.

                                 USE OF PROCEEDS

        All net proceeds from the sale of the shares of common stock covered by
this prospectus will go to the selling stockholder who is offering and selling
its shares. We will not receive any proceeds from the sale of the shares of
common stock by the selling stockholder. See "Plan of Distribution."


                              PLAN OF DISTRIBUTION





        CardioGenesis is registering the shares of common stock covered by this
prospectus for the selling stockholder. As used in this prospectus, "selling
stockholder" includes the pledgees, donees, transferees or others who later
receive the selling stockholder's interest for no additional consideration. We
will pay the costs and fees of registering the shares of common stock, but the
selling stockholder will pay any brokerage commissions, discounts or other
expenses relating to the sale of the shares of common stock.


        The selling stockholder may sell the shares of common stock on the
Nasdaq National Market, in the over-the-counter market or otherwise, at market
prices prevailing at the time of sale, at prices related to the prevailing
market prices, or at negotiated prices. The selling stockholder may sell some or
all of the shares of common stock in one or more of the following ways:

        -   a block trade in which a broker-dealer may resell a part of the
            block, as principal, in order to facilitate the transaction;

        -   purchases by a broker-dealer, as principal, and resale by the
            broker-dealer for its account;


        -   ordinary brokerage transactions and transactions in which a broker
            solicits purchasers; or,


        -   privately negotiated transactions.

        When selling the shares of common stock, the selling stockholder may
enter into hedging transactions. For example, the selling stockholder may:

        -   enter into transactions involving short sales of the shares of
            common stock by broker-dealers;

        -   sell shares of common stock short themselves and redeliver such
            shares to close out their short positions;

        -   enter into option or other types of transactions that require the
            selling stockholder to deliver shares of common stock to a
            broker-dealer, who will then resell or transfer the shares of common
            stock under this prospectus; or

        -   loan or pledge the shares of common stock to a broker-dealer, who
            may sell the loaned shares or, in the event of default, sell the
            pledged shares.

        In addition to selling its shares of common stock under this prospectus,
the selling stockholder may transfer its shares of common stock in other ways
not involving market makers or established trading markets, including directly
by gift, distribution, or other transfer.


        The selling stockholder may negotiate and pay broker-dealers
commissions, discounts or concessions for their services. Broker-dealers engaged
by the selling stockholder may allow other broker-dealers to participate in
resales. The selling stockholder and any broker-dealers involved in the sale or
resale of the shares of common stock may qualify as "underwriters" within the
meaning of the Section 2(11) of the Securities Act. In addition, the
broker-dealers' commissions, discounts or concessions may qualify as
underwriters' compensation under the Securities Act. The selling stockholder may
be subject to the prospectus delivery requirements of the Securities Act if the
selling stockholder qualifies as an "underwriter" under the Securities Act.

        The shares will be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in some
states the shares may not be sold unless they have been registered or



                                       18
   19

qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

        Under the applicable rules and regulations of the Securities and
Exchange Act, any person engaged in the distribution of the shares may not
simultaneously engage in market making activities with respect to our shares of
common stock for a period of two business days prior to the commencement of such
distribution. In addition, the selling stockholder will be subject to applicable
provisions of the Exchange Act and the associated rules and regulations under
the Exchange Act, including Regulation M, which provisions may limit the timing
of purchases and sales of shares by the selling stockholder. We will make copies
of this prospectus available to the selling stockholder and have informed it of
the need for delivery of copies of this prospectus to purchasers at or prior to
the time of any sale of the shares.


        We may suspend the use of this prospectus and any supplements due to
pending corporate developments, public filings with the SEC or similar events.


                               SELLING STOCKHOLDER


        The selling stockholder described below is a stockholder that is
offering and selling these shares covered by this prospectus which were
purchased by the selling stockholder in a transaction exempt from the
registration requirements of the Securities Act of 1933, as amended, pursuant to
Rule 506 from CardioGenesis pursuant to a share purchase agreement dated April
11, 2001 which closed on April 12, 2001. As part of the share purchase
agreement, CardioGenesis will not, for ninety (90) days after the closing date,
sell shares of it's common stock, options, warrants or any other securities that
can be converted into, or otherwise exchanged for, shares of common stock at a
conversion or exercise price less than the per share price for which
CardioGenesis sold these shares pursuant to the share purchase agreement. In the
event CardioGenesis does, during the ninety (90) day period, sell any shares of
it's common stock at, or any instruments that can be converted into or otherwise
exchanged for it's common stock exercisable at, a price per share less than the
per share price under the share purchase agreement, CardioGenesis will refund
the difference to the selling stockholder.

        The selling stockholder may donate or transfer as gifts some or all of
its CardioGenesis shares, or may transfer its shares for no additional
consideration to others. We will include any of these donees or transferees as a
selling stockholder in a prospectus supplement, if required.

        The selling stockholder has held no position or office or has had any
other material relationship with CardioGenesis or any of our affiliates within
the past three years other than as a result of its ownership of shares of our
common stock. The selling stockholder is not a broker/dealer or an affiliate of
a broker/dealer. The selling stockholder is an independent agency in the
administrative branch of the Wisconsin state government. Pursuant to s. 15.76,
Wis. Stats., it is governed by a board of nine trustees, six of whom are
appointed by the Governor with confirmation by the State Senate. Two trustees
are appointed by separate boards made up of representatives elected by
participants in the Wisconsin Retirement System, the public pension plan managed
by the selling stockholder. The remaining trustee is the Secretary of the State
Department of Administration or the Secretary's designee. Four of the trustees
appointed by the Governor must have at least ten years of investment experience
and one of the Governor's appointees must have at least ten years' experience in
a local government finance position. This information is based upon information
provided by the selling stockholder.


        The table below sets forth the following information regarding the
selling stockholder:

        -   The name of the selling stockholder;

        -   The number of shares of our common stock owned by the selling
            stockholder on the date of this prospectus prior to the offering for
            resale of any of the shares being registered by the registration
            statement of which this prospectus is a part;

        -   The number of shares of our common stock that may be offered for
            resale by the selling stockholder pursuant to this prospectus; and


                                       19
   20

        -   The number of shares of our common stock to be held by the selling
            stockholder after the resale of the offered shares.

(1)     Since the selling stockholder may offer all, some or none of its common
        stock, we cannot provide a definitive estimate of the number of shares
        the selling stockholder will hold after the offering. The shares
        beneficially owned after the offering column assumes the sale of all
        shares offered, and that the selling stockholder acquires no additional
        shares of common stock before the completion of this offering.


(2)     The percentage owned after offering column is based on 31,696,061 shares
        of CardioGenesis common stock outstanding as of March 30, 2001.


                                  LEGAL MATTERS

        Certain legal matters with respect to the shares of common stock offered
hereby will be passed upon for us by Gibson, Dunn & Crutcher LLP, Los Angeles,
California.

ITEM 17. UNDERTAKINGS

        The undersigned Registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
            a post-effective amendment to this Registration Statement:

            (i)   to include any prospectus required by Section 10(a)(3) of the
                  Securities Act,

            (ii)  to reflect in the prospectus any facts or events arising after
                  the effective date of the registration statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in this Registration


                                       21
   22

                  Statement. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high end of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the Commission pursuant to Rule
                  424(b) if, in the aggregate, the changes in volume and price
                  represent no more than 20 percent change in the maximum
                  aggregate offering price set forth in the "Calculation of
                  Registration Fee" table in the effective Registration
                  Statement, and

            (iii) to include any material information with respect to the plan
                  of distribution not previously disclosed in this Registration
                  Statement or any material change to such information in this
                  Registration Statement,

            provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
            if the information required to be included in a post-effective
            amendment by those paragraphs is contained in periodic reports filed
            with or furnished to the Commission by the registrant pursuant to
            Section 13 or Section 15(d) of the Exchange Act that are
            incorporated by reference in the Registration Statement;

        (2) That, for the purpose of determining any liability under the
            Securities Act, each such post-effective amendment shall be deemed
            to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof;

            To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering;

            That, for purposes of determining any liability under the Securities
            Act, each filing of the Registrant's annual report pursuant to
            Section 13(a) or Section 15(d) of the Exchange Act (and, where
            applicable, each filing of an employee benefit plan's annual report
            pursuant to Section 15(d) of the Exchange Act) that is incorporated
            by reference in this Registration Statement shall be deemed to be a
            new registration statement relating to the securities offered
            therein, and the offering of such securities at that time shall be
            deemed to be the initial bona fide offering thereof; and

            Insofar as indemnification for liabilities arising under the
            Securities Act may be permitted to directors, officers and
            controlling persons of the Registrant pursuant to the foregoing
            provisions, or otherwise, the Registrant has been advised that in
            the opinion of the Securities and Exchange Commission such
            indemnification is against public policy as expressed in the
            Securities Act and is, therefore, unenforceable. In the event that a
            claim for indemnification against such liabilities (other than the
            payment by the Registrant of expenses incurred or paid by a
            director, officer or controlling person of the Registrant in the
            successful defense of any action, suit or proceeding) is asserted by
            such director, officer or controlling person in connection with the
            securities being registered, the Registrant will, unless in the
            opinion of its counsel the matter has been settled by controlling
            precedent, submit to a court of appropriate jurisdiction the
            question whether such indemnification by it is against public policy
            as expressed in the Securities Act and will be governed by the final
            adjudication of such issue.

registrant certifies that it has reasonable grounds to believe that it meets all

authorized, in the City of Sunnyvale, State of California, on June 26, 2001.
