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 graft comprising:

a first graft body, said first graft body having a first graft body inlet end and a first graft body outlet end to define a flow passage therethrough; and

a second graft body, said second graft body having a second graft body inlet end and a second graft body outlet end to define a flow passage therethrough;

said second graft body inlet end being attachable in an overlapping relationship with said first graft body outlet end while inside of a vessel to define a continuous flow passage through said first graft body inlet end, said first graft body outlet end, said second graft body inlet end and said second graft body outlet end.

2. The graft of claim 1 wherein at least one of the first graft body and the second graft body is reinforced by a wire structure.

3. The graft of claim 2 wherein the wire structure is formed of a metal.

4. The graft of claim 2 wherein the wire structure is formed of a stainless steel.

5. The graft of claim 2 wherein the wire structure is formed of a biocompatible plastic.

6. The graft of claim 2 wherein the wire structure is sutured to the respective graft body.

7. The graft of claim 2 wherein at least one of the first graft body and the second graft body is a multi-layered graft body and the wire structure is sandwiched between layers of said multi-layered graft body.

8. The graft of claim 2 wherein at least a portion of one of the first graft body and the second graft body is made of PTFE.

9. The graft of claim 2 wherein the wire structure is disposed at least in part on an outside surface of the respective graft body.

10. The graft of claim 2 wherein the wire structure is disposed substantially on an inside surface of the respective graft body.

11. The graft of claim 2 wherein the wire structure is interwoven with the surface of the respective graft body.

12. The graft of claim 2 wherein the wire structure is X-ray detectable.

13. The graft of claim 1 wherein at least one of the first graft body and the second graft body comprises a wire structure, said wire structure having at least a portion adjacent to one of said first graft body inlet end, said first graft body outlet end, said second graft body inlet end, and said second graft body outlet end, the wire structure including a plurality of projecting apices and wherein said one of the ends includes and edge which is scalloped between projecting apices of the wire structure.

14. The graft of claim 1 wherein the second graft body is frusto-conical in shape.

15. The graft of claim 1 wherein the second graft body is substantially cylindrical.

16. The graft of claim 1 wherein one of the first graft body and the second graft body comprises a skirt portion.

17. The graft of claim 16 wherein said skirt portion is about 10 to about 15 mm in length.

18. The graft of claim 16 wherein said skirt portion is further provided with at least one linear reinforcement wire extending longitudinally along the respective graft body.

19. The graft of claim 16 wherein said skirt portion lacks any reinforcement wires.

20. The graft for treatment of aneurysms or occlusive diseases comprising:

a first graft body, said first graft body having an inlet end and an outlet end to define a first flow passage therethrough; and

a second graft body, said second graft body having an inlet end and an outlet end to define a second flow passage therethrough;

said inlet end of said second graft body being attachable in an overlapping relationship with said outlet end of said first graft body while inside of a vessel to define a continuous flow passage between said inlet end and said outlet end of said first graft body and said inlet end and said outlet end of said second graft body; and

wherein at least one of the inlet ends and the outlet ends is reinforced with a wire member which has a plurality of apices extending beyond at least a portion of the corresponding end.

21. A graft comprising:

a first graft body, said first graft body having an inlet end and an outlet end to define a first flow passage therethrough; and

a second graft body, said second graft body having an inlet end and an outlet end to define a second flow passage therethrough;

said inlet end of said second graft body being attachable in an overlapping relationship with said outlet end of said first graft body while inside of a vessel to define a continuous flow passage through said first flow passage and said second flow passage; and

wherein the graft is adapted to be placed in a lumen of a first vessel that intersects with a second vessel; and

wherein at least one of the said inlet end of said first graft body and said outlet end of said second graft body that is adjacent to a junction between the first vessel and the second vessel is reinforced with a wire member which has a plurality of apices extending beyond at least a portion of a respective end adjacent to said junction, and said plurality of apices extend across said junction such that the graft does not occlude the lumen of the second vessel.

22. A graft for treatment of aneurysms or occlusive diseases comprising:

a first graft body, said first body having an inlet end and an outlet end to define a flow passage therethrough; and

a second graft body, said second graft body having an inlet end and an outlet end to define a flow passage therethrough;

said inlet end of said second graft body being attachable in an overlapping relationship with said outlet end of said first graft body while inside of a vessel to define a continuous flow passage between said inlet end and said outlet end of said first graft body and said inlet end and said outlet end of said second graft body;

wherein at least one of the first graft body and the second graft body is circumferentially reinforced by a metal wire structure.

23. The graft of claim 22 wherein the metal wire structure comprises at least one wireform.

24. The graft of claim 23 wherein said at least one wireform has closed sinusoidal shape.

25. The graft of claim 22 wherein the metal wire structure comprises a plurality of wireforms.
