Abstract
The invention includes a medical device and more specifically relates to a valve found generally within a frame. In a preferred device, the frame preferably comprises a self-expanding stent frame, and the valve has at least one expandable and contractible pocket member within the stent frame for resisting and permitting fluid flow, respectively.

37. A percutaneous heart valve device, comprising:
-
a frame having a first configuration suitable for percutaneous vascular delivery to a vascular site for providing a heart valve, and a second, expanded configuration adapted for deployment at the vascular site;
said expanded configuration being generally cylindrical in shape and providing an inner lumen, said expanded configuration further providing a first frame end and a second frame end;
said expanded configuration of said frame providing a plurality of struts that reverse direction and thereby provide a plurality of bends with apexes occurring at said second frame end;
said first frame end providing an inlet end of the valve device, and said second frame end providing an outlet end of the valve device;
a flexible collagenous biomaterial;
said flexible collagenous biomaterial forming at least two flexible valve leaflets within said inner lumen;
said at least two flexible valve leaflets each extending substantially from said first frame end to said second frame end; and
said at least two flexible valve leaflets forming a valve orifice at the outlet end of said frame. - View Dependent Claims (38, 39)

45. A percutaneous heart valve device, comprising:
-
a frame having a first configuration suitable for percutaneous vascular delivery to a vascular site for providing a heart valve, and a second, expanded configuration adapted for deployment at the vascular site;
said expanded configuration providing a first frame end and a second frame end;
said expanded configuration of said frame providing a plurality of struts that reverse direction and thereby provide a plurality of bends with apexes occurring at said second frame end and wherein each of said apexes is substantially co-terminal with the other apexes;
said flexible collagenous biomaterial formed to provide at least two flexible valve leaflets;
said at least two flexible valve leaflets having cooperating leaflet edge portions, said cooperating leaflet edge portions having outer ends connected to said frame and extending inwardly therefrom to form a valve orifice at said second end of said frame. - View Dependent Claims (46, 47)
