Abstract

What is described herein is a endovascular tube or bifurcated prosthesis used for the repair of aneurysms or other vessel disease. This can be soft or hard occlusive disease. This prosthesis is constructed by fabricating a structure that consists of a textile or other polymeric material and through which is threaded a superelastic metal wire such as a nitinol, a ductile wire or other filament material. The textile can be a polymeric material. The wire provides the self-expandability of the current device. Ideally, the thickness of the device should be minimized, so that it can be delivered to the diseased site using a percutaneous procedure.

Claims

1. A prosthesis comprising a non-metallic woven graft material, said woven graft material having a plurality of openings in its structure;

and at least one essentially straight wire emplaced in said plurality of openings in an alternating fashion so as to describe a weave.

2. A prosthesis of claim 1 wherein the wire is a self-expanding alloy.

3. A prosthesis of claim 1 wherein the wire is an alloy which conforms to Young'"'"'s modulus.

4. A prosthesis of claim 1 wherein the graft is a Dacron®

weave.

5. A prosthesis of claim 1 wherein the graft is a Teflon®

weave.

6. The prosthesis of claim 1 wherein the prosthesis is self-expanding.

7. The prosthesis of claim 1 wherein the prosthesis is made with said wires placed circumferentially about said graft.

8. The prosthesis of claim 1 wherein the prosthesis is made with said wires placed longitudinally about said graft.

9. A method for placement of a graft, comprising:

providing a prosthesis comprising a non-metallic woven graft material, said woven graft material having a plurality of openings in its structure; and

at least one essentially straight wire emplaced in said plurality of openings in an alternating fashion so as to describe a weave.

10. Method of claim 9 wherein the wire is a self-expanding alloy.

11. Method of claim 9 wherein the wire is an alloy which conforms to Young'"'"'s modulus.

12. Method of claim 9 wherein the graft is a Dacron®

weave.

13. Method of claim 9 wherein the graft is a Teflon®

weave.

14. Method of claim 9 wherein the prosthesis is self-expanding.

15. Method of claim 9 wherein the prosthesis is made with said wires placed circumferentially about said graft.

16. Method of claim 9 wherein the prosthesis is made with said wires placed longitudinally about said graft.
