摘要:
A method of delivering a prosthetic heart valve to a native aortic valve is disclosed. The prosthetic heart valve comprises a radially compressible and expandable metallic stent and a flexible valvular structure. A delivery system comprises a selectively steerable section and a pusher member extending through a central lumen of the steerable section. The prosthetic heart valve is compressed and inserted into a distal end portion of the delivery system. The delivery system and prosthetic heart valve are advanced through a femoral artery and around an aortic arch. A pull wire is actuated for selectively controlling a curvature of the steerable section during advancement around the aortic arch. The pusher member is advanced for ejecting the prosthetic heart valve from the delivery system into the native aortic valve, wherein the prosthetic valve self-expands after ejection.
