ENDOLUMINAL CARDIAC AND VENOUS VALVE PROSTHESES AND METHODS OF MANUFACTURE AND DELIVERY THEREOF

摘要

This invention relates to prosthetic cardiac and venous valves and a single catheter device and minimally invasive techniques for percutaneous and transluminal valvuloplasty and prosthetic valve implantation.

主权项

1. An implantable valvular prosthesis, comprising:
a stent body member having luminal and abluminal surfaces thereof and a central annular opening along a central longitudinal axis of the stent body member; a proximal anchoring section disposed at the proximal end of the stent body comprising a plurality of stent struts which project radially outward away from the central longitudinal axis of the stent body member and wherein orientation of the struts provides interstices between adjacent struts to prevent the prosthesis from impinging upon an adjacent structure; a graft member comprising an outer graft member coupled to the abluminal surface of the stent body member and an inner graft member coupled to the luminal surface of the stent body member, wherein a terminal portion of the inner graft member is everted inwardly toward the central longitudinal axis of the stent body member; at least one biasing arm projecting from the stent body member and into the central annular opening of the stent body member; and at least one valve flap member formed by the terminal portion of the inner graft member coupled to the at least one biasing arm, the at least one valve flap member assuming a position, under zero pressure differential across the prosthesis, which occludes the central annular opening of the stent body member.
