1. A stent valve, suitable for placement in a vessel, the vessel further having a diameter and an inner lumenal surface, comprising:
- a) a stent having a diameter, a proximal end, and a distal end, the stent sized to permit contact with the inner lumenal surface of the vessel;
b) a valve having a proximal end and a distal end, the valve being at least partially located within an inner portion of the stent, wherein the valve comprises a biocompatible material.

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.

31. A radially-expandable stent valve device for placement in a body vessel, comprising:
-
a self-expanding stent frame, said self-expanding stent frame conformable to a first, contracted state adapted for delivery through a lumen of a delivery device, and a second, expanded state for conforming a lumen of the vessel;
a valve attached to said frame and functional to resist fluid flow in a first direction through said stent frame and permit fluid flow in a second direction through said stent frame opposite said first direction;
said valve comprising a compliant biocompatible material defining at least one pocket member within said frame, said pocket member having an opening for receiving fluid flowing in said first direction and adapted to thereupon expand, said pocket member further adapted to contract upon impingement with fluid flowing in said second direction; and
said biocompatible material sufficiently compliant and said pocket member defined wherein said valve remains functional after contraction of said stent frame to said first, contracted state and expansion of said stent frame to said second, expanded state. - View Dependent Claims (32)
