Woven implantable device

1. A prosthetic valve for implantation in a body vessel, said prosthetic valve having a lengthwise axis and comprising:

at least one flexible member movable between a first position that permits fluid flow in a first direction and a second position that substantially prevents fluid flow in a second direction, the at least one flexible member formed of a woven structure having a surface and an outer edge, the woven structure comprising a continuous weave of first and second materials forming the surface;

the first material including multiple fibers interwoven with the second material, wherein the multiple fibers extend from the continuous weave along the outer edge of the flexible member to form a structure perimeter formed only of the first material and defining the perimeter of the woven structure; and

a plurality of extensions formed of the first material, each extension of the plurality of extensions extending outward from the structure perimeter relative to said lengthwise axis of said prosthetic valve and adapted for engaging said body vessel;

wherein said prosthetic valve has a first, unexpanded configuration and a second, expanded configuration.

2. The prosthetic valve of claim 1 , wherein the second material comprises a remodelable material.

3. The prosthetic valve of claim 1 , wherein the second material comprises an extracellular matrix material (ECM).

4. The prosthetic valve of claim 1 wherein the second material comprises a synthetic material.

5. The prosthetic valve of claim 1 wherein the first material comprises a shape memory alloy.

6. The prosthetic valve of claim 5 wherein the shape memory alloy provides a memory shape for the flexible member in the expanded configuration.

7. The prosthetic valve of claim 1 wherein the woven structure comprises a continuous weave of first, second and third materials along the surface.

8. The prosthetic valve of claim 1 further comprising an opening defined in the woven structure.

9. The prosthetic valve of claim 8 , wherein the at least one flexible member comprises a pair of flexible members; and

wherein the pair of flexible members forms a member contact area when the flow is in the second direction.

10. The prosthetic valve of claim 1 , further comprising a support structure operably connected to the at least one flexible member.

11. The prosthetic valve of claim 1 , wherein the second material is provided as a sheet of material and the first material is at least partially woven into the sheet.

12. The prosthetic valve of claim 1 , wherein the first material comprises a shape memory alloy and the second material comprises a remodelable material.

13. The prosthetic valve of claim 12 , wherein the first material comprises a titanium nickel alloy.

14. The prosthetic valve of claim 12 , wherein the second material comprises an extracellular matrix material (ECM).

15. The prosthetic valve of claim 14 , wherein the ECM comprises small intestine submucosa (SIS).

16. The prosthetic valve of claim 12 , wherein the first material comprises a titanium nickel alloy and the second material comprises an extracellular matrix material (ECM).

17. The prosthetic valve of claim 1 , wherein the woven structure comprises a mesh formed from a uniform weave of the first material and the second material.

18. The prosthetic valve of claim 1 , wherein the woven structure comprises a mesh formed from a non-uniform weave of the first material and the second material.
