ABIOMED Announces Record Results; Q4 Revenue Up 28% to $13.8 Million;
                         Record VAD Shipments

    DANVERS, Mass.--(BUSINESS WIRE)--May 8, 2006--ABIOMED, Inc.
(NASDAQ: ABMD) today announced financial results for its fiscal fourth
quarter ended March 31, 2006. Revenue for the fiscal fourth quarter of
2006 was $13.8 million, up 28% compared to revenue of $10.8 million in
the same period of fiscal 2005. Revenue for the fiscal year 2006
reached $43.7 million, up 14% over fiscal year 2005 and up 70% over
the last two years.

    Recent financial and operating highlights include:

    --  Strong U.S. growth with a 28% increase in total revenue for
        the quarter and 134% growth in AB5000(TM) Consoles revenue.

    --  Total worldwide revenue for consoles (IMPELLA and AB5000) for
        the fourth quarter of fiscal 2006 increased 104%.

    --  Record number of patients supported on AB5000(TM) Ventricles
        during the quarter.

    --  Record number of Ventricular Assist Devices (VADs) shipped
        (IMPELLA, AB5000 and BVS 5000), representing a 17% increase in
        revenue for disposables compared to the fourth quarter of
        fiscal 2005.

    --  Increase in global distribution with the addition of four
        sales and clinical representatives. Sales and clinical
        headcount at the end of fiscal 2006 was 45, up approximately
        70% since the end of fiscal 2005.

    --  The fourth quarter reported loss was $3.7 million, or $.14 per
        share and the full year fiscal 2006 reported loss, including
        an in-process R&D charge of $13.3 million related to the
        IMPELLA acquisition, was $29.5 million.

    "We are pleased with our progress broadening our global reach and
the continued momentum and market acceptance of our new products such
as the AB5000 and IMPELLA," said Michael R. Minogue, Chairman, CEO and
President of ABIOMED. "Our strategy and investments in fiscal 2007 are
focused around continuing to expand our global distribution and the
introduction of five new products into the United States to establish
heart recovery as the standard of care for all acute events."
    ABIOMED forecasts fiscal 2007 revenue to be in the range of $49
million to $52 million, representing an increase of 12% to 19% over
fiscal 2006, depending on the timing of new product trials and
introductions. Based on our current strategy to broaden our portfolio
and distribution, ABIOMED expects a loss in fiscal 2007 of $13 million
to $16 million, excluding the effects of stock option expense, due to:
continued investments in R&D of $16 million to $20 million and
expansion of global distribution with a goal of two to four new hires
per quarter. The expected fiscal 2007 effect of expensing stock
options is approximately $4 million; therefore the expected GAAP loss
for fiscal 2007 is estimated at $17 million to $20 million.
    Financial information for the fourth quarter and full year of
fiscal 2006 is attached to this press release.
