SYSTEMS FOR REPLACING A NATIVE HEART VALVE AND AORTA WITH A PROSTHETIC HEART VALVE AND CONDUIT

摘要

A medical device includes an expandable conduit, a prosthetic heart valve and a delivery device, including a balloon catheter. The expandable conduit may include one or more inner or outer sleeves supported by a frame or stent. The sleeve(s) may be a bioprosthetic tissue wrapped, molded or sewn about the frame or stent. Coupled to an end of the expandable conduit is the prosthetic heart valve. The conduit and heart valve may be crimped on the balloon catheter for percutaneous deployment. The frame may be constructed of an expandable material for the conduit portion and an expandable material for the prosthetic heart valve portion. The prosthetic heart valve can be anchored at the native heart valve and then the conduit can be expanded into place to protect the aorta.
