Abiomed Announces Update on Impella(R) 2.5 510(k) Process.

DANVERS, Mass. -- Abiomed, Inc. (NASDAQ: ABMD) today announced it recently received a written response from the U.S. Food and Drug Administration (FDA) outlining four areas of concern for which they requested additional information related to the company's submission for 510(k) clearance of the Impella 2.5.

Two of the questions requested clarification and additional information related to labeling within the 510(k) submission. A third question requested additional information related to bench-testing of the device. A fourth question requested that the company provide an updated clinical review of the global experience with the Impella 2.5 since the original 510(k) submission, including up to date information from the U.S. safety pilot clinical trial for the Impella 2.5. The company plans to respond to this recent request for information.

"We continue to work diligently with the FDA to provide clarification on existing data and additional information related to our 510(k) clearance submission for the Impella 2.5," stated Michael R. Minogue, Chairman, President and CEO of Abiomed. "While there are no guarantees for a 510(k) clearance, we remain confident that we are on a 510(k) path with a potential clearance sometime between November 2007 and March 2008."

The clinical experience to-date with Impella 2.5 has been favorable, including its recently completed U.S. safety pilot clinical trial. The technology is now approved in more than 40 countries, and is available in Europe under the CE Mark. Impella has been the subject of more than 20 peer reviewed publications.
