 FDA Approves Abiomed's IDE for IMPELLA 5.0 Minimally Invasive Cardiac Support
 Systems; Advanced Medical Technology Indicated for Use with Low Cardiac Output
                             after Cardiac Surgery

    DANVERS, Mass.--(BUSINESS WIRE)--June 27, 2006--Abiomed, Inc.
(NASDAQ: ABMD) today announced conditional approval by the U.S. Food
and Drug Administration (FDA) of its Investigational Device Exemption
(IDE) for the IMPELLA 5.0 unique, catheter-based Circulatory Support
Systems. Clinical trials in the U.S. are to begin immediately. The
IMPELLA(R) RECOVER 5.0 devices are already available in Europe under
CE Mark approval and have been used to treat more than 250 patients in
Europe in need of cardiac support resulting from postcardiotomy
cardiogenic shock, myocarditis, low cardiac output post-acute
myocardial infarction, or post-coronary intervention procedures, or as
a bridge to other circulatory support devices, including Abiomed's
AB5000(TM) and BVS(R) 5000 Circulatory Support Systems.
    The pilot study in the United States for the IMPELLA 5.0 will
enroll up to 20 patients at seven U.S. sites including: the University
of Maryland, Massachusetts General Hospital, Lankenau Hospital in
Philadelphia, Robert Wood Johnson Hospital in New Jersey, New York
Presbyterian Hospital, Texas Heart Institute and Penn State Milton S.
Hershey Medical Center in Pennsylvania. The study will include
postcardiotomy patients who have been weaned from heart-lung machines
and whose hearts require added support to maintain good blood flow.
The study will enroll those patients that would typically need more
flow and hemodynamic support than provided by an Intra-Aortic Balloon
Pump (IABP).
    "The IMPELLA micro-VAD technology is likely a window into the
future where heart assist is headed. We look forward to evaluating the
safety of this device in patients whose hearts are weakened after
heart surgery. Because of the small size, they are assembled on a
catheter that can be placed through an artery and into the heart,"
said Bartley Griffith, M.D., Chief of Cardiac Surgery and Heart & Lung
Transplantation at the University of Maryland School of Medicine and
Principal Investigator of the study.
    "We are excited to receive this approval for the IMPELLA 5.0 as we
believe this technology will provide surgeons with a potent, minimally
invasive, circulatory support system. Abiomed's results with the
IMPELLA 5.0 in Europe have been excellent and we look forward to
ultimately bringing this technology to the United States through this
study," said Michael R. Minogue, Chairman, CEO and President of
Abiomed.

    ABOUT THE IMPELLA 5.0

    The IMPELLA 5.0 technology consists of catheters that can be
introduced percutaneously through a cut-down and surgically. Other
IMPELLA devices currently available in Europe under CE Mark approval
include the IMPELLA(R) 2.5, and the IMPELLA(R) RD.
    The IMPELLA 5.0 Pumps can achieve flows of up to 5.0 liters per
minute, and actively unload the ventricle, reducing myocardial
workload and oxygen consumption while increasing cardiac output and
coronary and end-organ perfusion.
    IMPELLA 5.0 devices have been the subject of more than 10 clinical
papers reporting European experiences. Recent studies have shown that
the IMPELLA 5.0 can provide effective and adequate support for
high-risk surgery patients, as well as patients presenting with
marginal cardiac output as well as severe cardiogenic shock.
    The IMPELLA 5.0 Support Systems are intended to be used for up to
seven days as left ventricular cardiac assist devices. The systems are
comprised of the IMPELLA mobile console, the IMPELLA bearing purger
and the IMPELLA 5.0 catheter based rotary blood pumps.

limited by Federal Law solely to investigational use in the United
States. Other IMPELLA devices are not yet available for sale in the
United States. The Company's AbioCor(R) Implantable Replacement Heart
was the subject of an initial clinical trial under an Investigational
Device Exemption from the United States Food and Drug Administration.
The AbioCor has not been approved for commercial distribution, and is
not available for use or sale outside of the initial clinical trial.
