More than a Cardiac Assist Company

Cardiovascular diseases are the world’s leading cause of death. One of the most prevalent is Congestive (CHF). In the U.S. alone, an estimated five million people suffer from CHF, with another half-million or more diagnosed each year. The five-year mortality rate is estimated at 50 percent. Thoratec is committed to lowering that figure. In that effort, we provide two complementary cardiac assist product lines—the Thoratec Ventricular Assist Device (VAD) System for short-term cardiac support and the HeartMate Left Ventricular Assist System (LVAS) for longer-term support. Together, these products address more indications than the products of any other cardiac assist device company. Our cardiac assist products, along with our unique family of vascular grafts, our ITC blood coagulation measurement products, and a large and growing pipeline of next-genera- tion devices in clinical trials or under development, make Thoratec a central resource for treatment offerings for cardiac surgeons, cardiologists and their patients. More Ways to Manage CHF

More than short-term heart failure assistance. Thoratec has a long-term vision.

At any given time, there are 4,000 or more people on the U.S. national transplant waiting list.

Post-Cardiotomy Recovery (PC) benefits from the use of VADs to treat patients recovering from open-heart surgery. Typically, the maximum time a patient can be supported by bypass equipment is six hours. A small percentage of patients who are unable to be weaned from bypass equipment after surgery require additional

Therapeutic Recovery (BTR) is the largest potential VAD indication, estimated at approximately $5 billion. While not yet an approved indication for circulatory support devices, clinicians estimate that a significant number of CHF patients can recover use of their natural hearts after being supported by a VAD. We are aware of approximately two dozen patients who have had that experience while supported by a Thoratec VAD System. We are currently pursuing FDA approval for this indication.

Alternative to Transplant (ATT) is the use of an implantable device to augment or replace the entire func- tion of the patient’s natural heart. We estimate the size of this market opportunity at up to 100,000 patients annually in the U.S. alone. More than a chance to live. A chance to live independently.

HeartMate LVAS

• THE LEADER IN LONG-TERM CARDIAC SUPPORT

• APPROVED FOR BTT SINCE 1994

Alternative to Transplant (ATT) Since the mid-1990’s, the HeartMate LVAS and Thoratec Potential Patient Population (U.S.) VAD System have been used to treat more than 4,500 patients, accounting for about two-thirds of the cardiac assist market. That success is due, in part, to our ability to handle more of the short and long-term indications clinicians encounter every day. The HeartMate LVAS provides longer-term cardiac 100,000 POTENTIAL (ATT) support—to date over 900 cumulative patient years. Currently, two versions of the HeartMate LVAS are available:
