Abstract

The present invention is directed to a prosthesis for implantation within a body lumen. The prosthesis includes a biocompatible elongate intraluminal liner in the form of a graft, with a biocompatible adhesive being disposed on an exterior surface of the graft. The adhesive is active in an intraluminal environment so as to bond the exterior surface of the graft to an intraluminal surface of said body lumen, such as the interior of a blood vessel.

Claims

1. A method of implanting a prothesis within a body lumen comprising:

providing a prosthesis comprising a biocompatible elongate intraluminal liner, said liner including an elongate tubular body having a length, an interior surface, and an exterior surface;

applying a biocompatible adhesive continuously along said exterior surface of said liner;

delivering said prosthesis to an area of implantation within a body lumen; and

expanding said prosthesis so as to cause said adhesive on said exterior surface of said liner to contact an intraluminal surface of said body lumen, wherein said exterior surface and said adhesive are in continuous contact with said body lumen;

wherein said adhesive is held within frangible encapsulants, said encapsulants being disposed on said exterior surface of said tubular body and being capable of rupturing when compressed between said tubular body and said lumen so as to release said adhesive and thereby bonding said exterior surface of said liner to an intraluminal surface of said body lumen.

2. The method of claim 1, wherein said adhesive is bioabsorbable.

3. The method of claim 1, wherein said adhesive is a curable polymer adhesive.

4. The method of claim 1, wherein said adhesive is a pressure sensitive adhesive.

5. The method of claim 1, wherein said adhesive is selected from the group consisting of polyurethanes, cyanoacrylates, silicones, (meth)acrylates, and combinations thereof.

6. The method of claim 1, wherein said adhesive is a biological sealant capable of bonding said liner to said intraluminal surface of said body lumen.

7. The method of claim 6, wherein said biological sealant is selected from the group consisting of fibrin, collagen, poly(L-glutamic acid), gelatin based hydrogels, N-vinyl pyrrolidone, and mixtures and combinations thereof.

8. The method of claim 1, wherein said liner includes a plurality of pores sufficient to permit the ingrowth of body tissue.

9. The method of claim 8, wherein said adhesive is disposed through at least one of said pores in said liner.

10. The method of claim 1, wherein said liner comprises an extruded tube.

11. The method of claim 1, wherein said liner is formed from a polymeric sheet.

12. The method of claim 1, wherein said liner comprises a textile tubular body.

13. The method of claim 11, wherein said textile tubular body is formed from a weave, knit, or braid construction.

14. The method of claim 1, wherein said tubular body is formed from spun filaments.

15. The method of claim 1, wherein said liner is formed from a material selected from the group consisting of polyesters, polypropylenes, polyethylenes, polyurethanes, polytetrafluoroethylenes, polycarbonate-polyurethanes, poly-alpha-hydroxy-acids, and combinations thereof.

16. The method of claim 1, wherein said liner is expandable from an insertion diameter to an implantation diameter greater than said insertion diameter so that at the implantation diameter said liner is conformable to the intraluminal surface of said body lumen.

17. The method of claim 1, further including a removable cover over said adhesive.

18. The method of claim 1, further including a concentric tubular body within said liner.

19. A method of implanting a prosthesis within a body lumen comprising:

providing a prosthesis comprising a biocompatible elongate intraluminal liner, said liner including an elongate tubular body having pores, a length, an interior surface, and an exterior surface;

delivering said prosthesis to an area of implantation within a body lumen;

applying a biocompatible adhesive along said interior surface of said liner; and

expanding said prosthesis so as to cause said adhesive on said interior surface to migrate through said pores of said liner to contact an intraluminal surface of said body lumen, wherein said exterior surface and said adhesive are in continuous contact with said body lumen.
