ADDING MULTIMEDIA Abiomed Receives HDE Supplement Approval for AbioCor(R) Artificial Heart.

* Approval Enables Commercial Launch in the United States 

* AbioCor the Only Treatment Option for Bi-Ventricular Heart Failure Patients Not Eligible for Transplant

DANVERS, Mass. -- Abiomed, Inc. (NASDAQ: ABMD) today announced that it has received U.S. Food and Drug Administration (FDA) Humanitarian Device Exemption (HDE) supplement approval on system upgrades for its AbioCor([R])Implantable Replacement Heart (AbioCor). The AbioCor is intended to replace the severely damaged native heart for patients who are not eligible for a transplant and have no other treatment alternative. The AbioCor sustains the body's circulation and is designed to extend the lives of patients who would otherwise die of heart failure, while also offering a probable benefit for a satisfactory quality of life. The AbioCor is the first completely self-contained artificial heart that may allow patients more time at home, without wires or tubes piercing through their skin. This technology provides patients with complete mobility and remote diagnostics.

"This is a momentous day for Abiomed and advanced heart failure patients who cannot recover their natural heart or receive a transplant. We have selected leading U.S. hospitals committed to the AbioCor program and expect patient implants with AbioCor to commence in early 2008," said Michael R. Minogue, Chairman, CEO and President of Abiomed.

Abiomed has selected four sites to date as AbioCor Centers including: The Johns Hopkins Hospital in Baltimore, MD; Robert Wood Johnson University Hospital in New Brunswick, NJ; Texas Heart Institute at St Luke's Episcopal Hospital in Houston, TX; and St. Vincent's Hospital in Indianapolis, IN.

HDE approval allows the AbioCor to be made available to a limited patient population, with no more than 4,000 patients receiving the technology in the United States each year. Abiomed expects to charge $250,000 per AbioCor unit in a controlled roll-out at up to five U.S. centers.

ABOUT THE ABIOCOR

The AbioCor([R])Implantable Replacement Heart is one of the most sophisticated medical devices ever developed and is designed to extend the lives of patients who would otherwise die of heart failure. The AbioCor can potentially offer an improved quality of life so that a patient can be mobile and continue a productive lifestyle. The AbioCor is the only artificial heart without wires piercing through the skin, reducing the chance of infection. Its remote diagnostics allow patients to return home where they can resume normal activities including bathing. The AbioCor is able to pump blood through the body, simulating the rhythm of a heartbeat. The complete AbioCor system consists internally of a thoracic unit, a rechargeable battery, a miniaturized electronics package, a power receiver coil, and externally, a power transmitter coil, power and battery pack, handheld alarm monitor and sophisticated computer console.

Abiomed continues to develop next-generation total artificial heart technology, the AbioCor II, in order to provide life-saving circulatory support to more patients in bi-ventricular heart failure. Currently in preclinical evaluation, this technology has the potential to last up to five years and is approximately 30 percent smaller than the AbioCor.
