Abstract
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.
Claims25
An implantable valvular prosthesis, comprising:
- a. 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;
- b. 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;
- c. at least one biasing arm projecting from the stent body member and into the central annular opening of the stent body member;
- d. 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.

An implantable valvular prosthesis, comprising:
- a. a stent body member having luminal and abluminal surfaces thereof, a central annular opening along a central longitudinal axis of the stent body member, a proximal anchoring section and a distal anchoring section, at least one of the proximal anchoring section and the distal anchoring section comprising a diametrically enlarged section of the stent body member;
- b. a graft member covering at least a portion of at least one of the luminal and abluminal surfaces of the stent body member;
- c. at least one biasing arm projecting from the stent body member and into the central annular opening of the stent body member;
- and
- d. at least one valve flap member coupled to the at least one biasing arm and to at least a portion of the graft member, 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.
