WHRT World Heart Corp. (MM)

World Heart Corporation (WorldHeart) (Nasdaq:WHRT), a developer of mechanical circulatory systems, announced today that Tampa General Hospital (Tampa General) in Tampa, Florida has successfully implanted its first Levacor Ventricular Assist Device (VAD). Tampa General is the sixth implanting site nationwide in the Levacor VAD Bridge-to-Transplant (BTT) Study. This is the 15th implant with the Levacor VAD since the inception of the BTT Study.

WorldHeart also announced that three refinements are being made to its Levacor VAD based on initial experience. As a result, enrollment will continue to be slow in the BTT Study until the refinements are completed. These refinements are the projection of the inflow cannula into the ventricle, the elimination of a false alarm that has led to controller exchanges and the optimization of surface finishing/coating manufacturing processes. WorldHeart expects that implementation will take approximately two months, and anticipates that Study enrollment will accelerate once the refinements are complete.

"We are very excited to add Tampa General to the list of implanting centers and are encouraged by many of the BTT Study findings to date," noted Mr. J. Alex Martin, President and CEO. "However, we feel that it's worthwhile to implement these refinements. The Levacor VAD is a highly innovative device and we intend to maximize all of its potential attributes for the benefit of the patients who receive it."

About the Levacor VAD and World Heart Corporation

The Levacor VAD is the only fully magnetically levitated, bearingless, implantable centrifugal pump to move into clinical trials. By using magnetic levitation to fully suspend a spinning rotor, the Levacor VAD's only moving part, the pump is designed to eliminate wear and to provide unobstructed clearances for blood flow across a wide range of operation.
