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. An implantable prosthesis comprising:

a biocompatible elongate liner having an interior surface and an exterior surface and a plurality of pores sufficient to permit ingrowth of body tissue; and

at least one encapsulated biocompatible adhesive disposed on said interior surface of said liner;

wherein said adhesive extends through the pores of said liner and is active in an intraluminal environment so as to anchor said liner to an intraluminal surface of a body lumen.

2. The prosthesis of claim 1, wherein said adhesive is disposed within said pores.

3. The prosthesis of claim 1, wherein said adhesive comprises a member selected from the group consisting of bioabsorbable adhesives, curable polymer adhesives, pressure sensitive adhesives and combinations thereof.

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

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

6. The prosthesis of claim 5, 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.

7. The prosthesis of claim 1, wherein said adhesive is held within frangible encapsulants.

8. The prosthesis of claim 1, further comprising a mechanical support.

9. The prosthesis of claim 8, wherein said adhesive also bonds said mechanical support to said liner.

10. The prosthesis of claim 8, wherein said mechanical support comprises a radially expandable stent.

11. The prosthesis of claim 1, wherein said liner comprises a member selected from the group consisting of an extruded tube, a polymeric sheet, and a textile tubular body.

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

13. The prosthesis of claim 1, wherein said liner is formed from spun filaments.

14. The prosthesis 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.

15. The prosthesis 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.

16. The prosthesis of claim 1, further including a concentric tubular body within said liner.
