1. A percutaneous heart valve device, comprising:
- a self-expandable frame having a first condition suitable for percutaneous vascular delivery to a vascular site for providing a heart valve, and a second, expanded condition adapted for deployment at the vascular site,said expanded condition providing an inner lumen and including a first frame end and a second frame end, said first frame end having a perimeter of a different length than the perimeter of said second frame end; and
a plurality of flexible valve leaflets located within the inner lumen of said frame, said plurality of flexible valve leaflets comprised of pericardium and each having a proximal end and a distal end, said leaflet proximal ends having cooperating leaflet edge portions having outer ends connected to said frame at a first intermediate location along the length of said frame, said leaflet edge portions extending inwardly from said frame and associating to provide a valve orifice within the lumen of said frame,said plurality of flexible valve leaflets extending only partially along the length of said frame, wherein said leaflet distal ends are spaced proximally from an inlet end of said heart valve device, and each include a leaflet apex attached to said frame with a plurality of sutures extending in a generally lateral direction around a portion of the circumference of said frame, said leaflet apexes attached to said frame at a second intermediate location along the length of said frame, said second intermediate location spaced distally from said first intermediate location along said frame.

2. A percutaneous heart valve device, comprising:
-
a self-expandable frame having a first condition suitable for percutaneous vascular delivery to a vascular site for providing a heart valve, and a second, expanded condition adapted for deployment at the vascular site, said expanded condition providing an inner lumen and including a longitudinal frame segment having a generally cylindrical shape, said longitudinal frame segment providing a first end and a second end, said first end providing an inlet end of the heart valve device; and a valve arrangement residing within the inner lumen of said frame, said valve arrangement comprising a material in sheet-form and including a plurality of flexible valve leaflets each having a proximal end and a distal end, said leaflet proximal ends having cooperating leaflet edge portions having outer ends connected to said frame at a first intermediate location along the length of said frame, said leaflet edge portions extending inwardly from said frame and associating to provide a valve orifice within the lumen of said frame, said plurality of flexible valve leaflets extending only partially along the length of said frame, wherein said leaflet distal ends are spaced proximally from said first end of said longitudinal frame segment, and each include a leaflet apex attached to said frame with a plurality of sutures extending in a generally lateral direction around a portion of the circumference of said longitudinal frame segment, said leaflet apexes attached to said frame at a second intermediate location along the length of said frame, said second intermediate location spaced distally from said first intermediate location along said frame. - View Dependent Claims (3, 4, 5, 6, 7)
