Abiomed Announces Positive Reimbursement Recommendation at Medicare Evidence Development & Coverage Advisory Committee Meeting.

Panel Recommends Reimbursement Policy to Cover HDE Approved Technologies Such as the AbioCor

DANVERS, Mass. -- Abiomed, Inc. (NASDAQ: ABMD) today announced a positive recommendation by the Medicare Evidence Development & Coverage Advisory Committee (MedCAC), formerly known as the Medicare Coverage Advisory Committee, to include Humanitarian Device Exemption (HDE) approved technologies as covered "items or services" in the Medicare clinical trial policy. CMS generally follows the recommendations of its committee and incorporates such recommendations into coverage policy. CMS plans to issue a draft of its clinical trial policy in April 2007 and a final decision is slated for July. This recommendation is a significant reimbursement milestone and could allow future coverage of Abiomed's AbioCor([R]) Implantable Replacement Heart which was approved in September under an HDE.

"We look forward to working with the Centers for Medicare & Medicaid Services (CMS) as they assess their coverage for new, life-saving treatments like the AbioCor," said Michael R. Minogue, Chairman, CEO and President of Abiomed. "As we progress with the post-market study of the AbioCor, we hope to be able to partner with CMS and private insurers so that patients in bi-ventricular heart failure, who are not candidates for transplant, can have access to the technology."

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 are not candidates for heart transplant and would otherwise die of biventricular 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.

Under its HDE approval, the AbioCor will be available to a limited patient population in the United States under this approval, with no more than 4,000 patients receiving the technology each year. In order to ensure the highest standards of patient care, Abiomed intends to make the AbioCor available through a controlled roll-out at approximately five to ten heart hospitals in the United States, including qualified clinical trial sites and additional qualified centers once they have completed a comprehensive and rigorous training program. Under HDE approval, the FDA may request a panel review of the post-approval study data.

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.
