Abstract
Improvements to prosthetic heart valves and grafts for human implantation, particularly to methods and apparatus for coupling a prosthetic heart valve with an artificial graft during a surgical procedure to replace a defective heart valve and blood vessel section, e.g., the aortic valve and a section of the ascending aorta, are disclosed. An annular exterior surface of the prosthetic heart valve is fitted within a vascular graft lumen to dispose the vascular graft proximal end overlying the annular exterior surface, and the proximal end of an elongated vascular graft is compressed against the valve annular exterior surface in a manner that inhibits blood leakage between the vascular graft and the prosthetic heart valve.
