Abstract
A method of implanting a collapsible prosthetic heart valve is disclosed. The prosthetic heart valve includes three biological leaflets mounted within a self-expanding tubular leaflet frame formed of nitinol. The method comprises loading a collapsed prosthetic heart valve into a distal end of a delivery tube. The distal end of the delivery tube is inserted into a vasculature of a patient and positioned proximal to an aortic valve. The prosthetic heart valve is expelled into an annulus of the aortic valve and expanded. The prosthetic heart valve includes cusp positioners that engage sinus cavities above the valve annulus and rotationally orient the prosthetic valve. Preferred embodiments of the cusp positioners do not occlude the coronary arteries.
