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 for treatment of aneurysms or occlusive diseases comprising:

a primary graft body, said primary graft body having a primary graft flow lumen therethrough, said primary graft body comprising a first portion and a second portion; and

a supplemental graft body, said supplemental graft body having a secondary graft flow lumen therethrough, said supplemental graft body comprising a first end and a second end, said first end of said supplemental graft body being dockable to said second portion of said primary graft body while inside of a vessel to define a single flow lumen which transfers substantially all flow between said primary graft flow lumen and said secondary graft flow lumen.

2. The graft as defined in claim 1, wherein said primary graft body is circumferentially reinforced at locations along its length by a plurality of separate spaced apart wires.

3. The graft as defined in claim 2, wherein each of said separate spaced apart wires comprises two opposing ends, said ends being joined together on the outside surface of said primary graft body.

4. The graft as defined in claim 3, wherein said ends are joined together to form a tail.

5. The graft as defined in claim 2, wherein at least one of the reinforcement wires is interwoven with said primary graft body.

6. The graft as defined in claim 2, wherein at least one of the reinforcement wires is attached to said primary graft body via sutures.

7. The graft as defined in claim 2, wherein at least one of the reinforcement wires is attached to said primary graft body via adhesive.

8. The graft as defined in claim 1, wherein said supplemental graft body is circumferentially reinforced at locations along its length by a plurality of separate, spaced apart wires.

9. The graft as defined in claim 8, wherein each of said separate wires comprise two opposing ends, said ends being joined together on the outside surface of said supplemental graft body.

10. The graft as defined in claim 9, wherein said ends are joined together to form a tail.

11. The graft as defined in claim 8, wherein at least one of the reinforcement wires is interwoven with said supplemental graft body.

12. The graft as defined in claim 8, wherein at least one of the reinforcement wires is attached to said supplemental graft body via sutures.

13. The graft as defined in claim 8, wherein at least one of the reinforcement wires is attached to said supplemental graft body via adhesive.

14. The graft as defined in claim 2, wherein at least one of the reinforcement wires has a different amplitude than the next adjacent wire.

15. The graft as defined in claim 8, wherein at least one of the reinforcement wires has a different amplitude than the next adjacent wire.

16. The graft as defined in claim 2, wherein one of the reinforcement wires is located at one end of the primary graft body and has alternate crests or apices extending beyond said one end of the primary graft body.

17. The graft as defined in claim 1, wherein material of said primary graft body is crimped along its length.

18. The graft as defined in claim 1, wherein material of said supplemental graft body is crimped along its length.

19. The graft as defined in claim 1, wherein said primary graft body and said supplemental graft body are formed of a thin biocompatible material.
