Abstract

An intraluminal graft includes a tubular graft body extending along a cylindrical axis, a plurality of wires spaced apart from each other and arranged to circumferentially reinforce said tubular graft body along a substantial portion of its length, and a body surface including an inner surface region and an outer surface region. The body surface defines a plurality of apertures extending from an exterior space, and a first portion of a first wire is in the interior space while a second portion of the first wire is in the exterior space.

Claims

1. A prosthesis comprising:

a bifurcated base graft structure which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; and

a second graft structure which is adapted to be anchored within one of the flow lumens of said bifurcated base graft structure to form a continuous extension of that lumen;

wherein at least one of the bifurcated base graft structure and the second graft structure comprises a first end, a second end and a wire member having at least a portion adjacent to the first end, the wire member including a plurality of projecting apices, and wherein the first end includes an edge which is scalloped between projecting apices of the wire member.

2. The prosthesis of claim 1 wherein the second graft structure is adapted to be anchored within one of the divergent flow lumens.

3. The prosthesis of claim 1 wherein said wire member is sutured to the prosthesis.

4. The prosthesis of claim 1 wherein at least a portion of one of the bifurcated base graft structure and the second graft structure comprises PTFE.

5. The prosthesis of claim 1 wherein at least a portion of one of the bifurcated base graft structure and the second graft structure comprises a biocompatible material.

6. The prosthesis of claim 1 wherein the wire member is formed of a metal.

7. The prosthesis of claim 1 wherein the wire member is formed of stainless steel.

8. The prosthesis of claim 1 wherein the wire member is disposed at least in part on an outside surface of the prosthesis.

9. The prosthesis of claim 1 wherein the wire member is disposed substantially on an inside surface of the prosthesis.

10. The prosthesis of claim 1 wherein the wire member is interwoven with the surface of the prosthesis.

11. The prosthesis of claim 1 wherein the wire member is X-ray detectable.

12. The prosthesis of claim 1 wherein the second graft structure is frusto-conical in shape with a diameter that increases or decreases along the length of the second graft structure.

13. The prosthesis of claim 1 wherein the second graft structure is substantially cylindrical.

14. The prosthesis of claim 1 wherein a downstream end of the bifurcated base graft structure is provided with at least one resilient reinforcement wire.

15. A prosthesis comprising:

a bifurcated base graft structure which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; and

a second graft structure which is adapted to overlap and be attached to one of the flow lumens of said bifurcated base graft structure to form a continuous extension of that lumen;

wherein at least one of the bifurcated base graft structure and the second graft structure comprises a first end and a second end, and wherein at least one of the first and the second ends is reinforced with a wire structure which has a plurality of apices extending beyond at least a portion of the corresponding end.

16. The prosthesis of claim 15 wherein the first and the second ends are each reinforced with a wire structure which has a plurality of apices extending beyond the first and the second ends.

17. A prosthesis comprising:

a bifurcated base graft structure which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; and

a second graft structure which is adapted to overlap and be attached to one of the flow lumens of said bifurcated base graft structure to form a continuous extension of that lumen;

wherein the second graft structure is adapted to overlap and be attached to one of the divergent flow lumens.

18. The prosthesis of claim 17 wherein one of the bifurcated base graft structure and the second graft structure is reinforced by a metal wire structure.

19. The prosthesis of claim 18 wherein at least a portion of said metal wire structure is X-ray detectable.

20. The prosthesis of claim 18 wherein the metal wire structure comprises a plurality of wireforms.

21. The prosthesis of claim 20 wherein each wireform of the plurality of wireforms has a closed sinusoidal shape.

22. The prosthesis of claim 17 wherein each of the bifurcated base graft structure and the second graft structure comprises an inlet end and at least one outlet end;

wherein the prosthesis is adapted to be placed in a lumen of a first vessel that intersects with a second vessel such that at least one of the inlet end of the bifurcated base graft structure and the outlet end of the second graft structure is placed adjacent said intersection between the first vessel and the second vessel; and

wherein the at least one of the inlet end of the bifurcated based graft structure and the outlet end of the second graft structure is provided with a wire structure which has a plurality of apices extending beyond at least a portion of the corresponding inlet end of the bifurcated base graft structure and outlet end of the second graft structure and across a lumen of the second vessel without occluding it.

23. A prosthesis comprising:

a bifurcated base graft structure which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; and

a second graft structure which is adapted to overlap and be attached to one of the flow lumens of said bifurcated base structure to form a continuous extension of that lumen;

wherein at least one of the bifurcated base graft structure and the second graft structure comprises a first end and a second end, and wherein at least one of the first and second ends is provided with a wire structure which has a plurality of apices extending beyond at least a portion of the corresponding end such that the wire structure apices extend across a lumen of a first vessel that opens into a second vessel in which the prosthesis is being placed without occluding the lumen of said first vessel.
