Heart failure is a degenerative, terminal disease affecting over 20 million patients worldwide. Approximately 1 million patients suffer from Class IV heart failure, the end stage of the disease. Heart transplantation is considered the best available treatment option, but only approximately 3,000 donor hearts become available worldwide each year. LVADs are used to bridge patients until a donor heart becomes available (so called Bridge-to-Transplant therapy) or, increasingly, as a long term alternative to transplantation (so called Destination Therapy.)

The HeartWare Ventricular Assist System features a miniaturized implantable centrifugal pump capable of producing up to 10 liters per minute of blood flow. The pump is designed to be implanted above the diaphragm, directly adjacent to the heart, thereby avoiding the abdominal surgery generally required to implant competing devices.

HeartWare has completed enrollment of a 50-patient international clinical trial. The Company received CE Mark approval for the System in January 2009 and the System is now commercially available in Europe. In the United States, the System is the subject of an ongoing Bridge-to-Transplant clinical trial under which HeartWare will enroll up to 150 patients at a maximum of 28 participating centers.

HeartWare is also developing a portfolio of further miniaturized devices, implantable by progressively less invasive surgery.

HeartWare's corporate headquarters are in Framingham, Massachusetts. The Company's operating and manufacturing activities are based in Miami Lakes, Florida.
