    --  Impella 2.5 High-Risk PCI Pivotal Trial Conditionally Approved
        in Late Fiscal Q2 2008

    --  Customer Orders of $1.6 million for Impella 2.5 Pivotal Trial
        and AbioCor Not Included in Fiscal Q2 Revenue

    --  Impella Disposable Revenue up 140%


    DANVERS, Mass.--(BUSINESS WIRE)--Nov. 8, 2007--Abiomed, Inc.
(NASDAQ: ABMD) today announced fiscal second quarter 2008 revenue of
approximately $11.4 million, up approximately 5% compared to revenue
of $10.9 million for the same period of fiscal 2007. Revenue for the
six months ended September 30, 2007 was approximately $25.4 million,
up approximately 6% compared to revenue of approximately $23.9 million
in the first six months of fiscal 2007.

    Recent financial and operating highlights include:

    --  While there are no guarantees for a 510(k) clearance, current
        informal FDA feedback is that the Impella(R) 2.5 is on the
        substantially equivalent (SE) path, and that the device does
        not pose any new questions as compared to the predicate
        devices. Abiomed is preparing responses to the FDA questions
        on the 510(k) submission for the Impella 2.5.

    --  During the second quarter of fiscal 2008 compared to the
        second quarter of fiscal 2007, Impella disposable revenue
        increased 140%, AB5000 disposable revenue increased 20%, and
        BVS(R) 5000 disposable revenue declined 10%.

    --  Impella console revenue increased 100% and AB5000(TM) console
        revenue decreased 48%. The Company's iPulse(TM) combination
        console continues to be under regulatory review by the FDA for
        PMA supplement approval. The Company expects FDA supplement
        approval for the iPulse in the third quarter of fiscal 2008,
        which ends December 31, 2007; however there is no guarantee
        that approval will be received.

    --  Abiomed received approval in late fiscal Q2 2008 for one of
        its two submissions for a pivotal study with Impella 2.5. The
        high-risk PCI (percutaneous coronary intervention) pivotal
        study approval is for the Impella 2.5 at up to 150 hospitals.

    --  Customer orders of $1.6 million related to both the Impella
        2.5 pivotal trial and AbioCor were not included in revenue for
        the second quarter of fiscal 2008. Impella orders were
        deferred due to investigational review board (IRB) processes
        and training requirements.

    --  Abiomed is waiting for FDA approval for its Impella 2.5 acute
        myocardial infarction (AMI) shock pivotal trial, which is
        expected sometime in the quarter ending December 31, 2007;
        however there is no guarantee that approval will be received.

    --  The second quarter of fiscal 2008 GAAP net loss was $9.4
        million, or $.29 per share, which included stock option and
        other stock-based compensation expense of $1.3 million, or
        $.04 per share. The net loss for the second quarter of fiscal
        2007 was $8.7 million, or $.33 per share and included stock
        option and other stock-based compensation expense of $1.6
        million, or $.06 per share.

    "We were pleased with the global Impella revenue growth for the
summer quarter, especially in Europe. Overall, we are excited and
prepared to enter the U.S. market with our strategic platforms of
Impella and iPulse products when we receive FDA approvals," said
Michael R. Minogue, Chairman, CEO and President of Abiomed. "We have
started the Impella 2.5 pivotal trial for high-risk PCI following a
very successful TCT Conference and we continue to work toward
obtaining 510(k) clearance of the Impella 2.5 and approval to begin
our Impella 2.5 AMI pivotal study. As we stated at the start of the
fiscal year, the revenue ramp in the U.S. is dependent on regulatory
approvals and would be second half loaded."

    Abiomed is reaffirming its full-year fiscal 2008 revenue growth
estimate of greater than 20%, based on the Company's expected timing
of U.S. clinical trials and global regulatory approvals of new
products (Impella 2.5, iPulse supplement, and AbioCor supplement).

    The Company will release complete second fiscal quarter 2008
results on November 8, 2007, and host a conference call to discuss the
results that day at 8:00 a.m. ET. Michael R. Minogue, Chairman, Chief
