Speech Title: Matched ventricular assist devices based on ultrasonic motors
Abstract: Worldwide the number of heart failure patients exceeds 23 million, in which 5-10% of total heart failure patients may become unresponsive to conventional treatments. Although heart transplantation is a gold standard of treatment for heart failure, heart transplantation is limited by the availability of donor hearts. Fortunately rapid advances in technology have enabled durable mechanical circulatory support emerged as an increasingly viable therapeutic option for treatment of heart failure patients as bridge to heart transplantation, or life time support as destination therapy. These mechanical circulatory support devices provide effective hemodynamic support, high device reliability and significant improvements in patient status. However mechanical circulatory support therapy is accompanied complications including pump thrombosis, bleeding, stroke, and right ventricle failure. The major reasons are that ventricle assist devices usually provide constant blood flow, which could not completely match the timing and blood flow requirements from the diseased heart.
