An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE
An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures.
1. An endovascular device comprising: a polymeric tube having opposed first and second open ends;an inflatable structure integral with or permanently secured to at least a portion of said polymeric tube; anda non-inflatable expansion member disposed at one of said first and second opposed open ends;
1. An endovascular device comprising: a polymeric tube having opposed first and second open ends;an inflatable structure integral with or permanently secured to at least a portion of said polymeric tube; anda non-inflatable expansion member disposed at one of said first and second opposed open ends;wherein the inflatable structure is inflatable with an inflation fluid to provide an inflated state such that the inflated state conforms to the shape of a bodily lumen. 2. The device of claim 1, wherein the inflatable structure in the inflated state seals a bodily lumen from blood flow. 3. The device of claim 1, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. 4. The device of claim 1, wherein the inflatable structure is a polymeric structure. 5. The device of claim 1, wherein the polymeric tube comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane, polyethylene and polyethylene terephthalate (PET). 6. The device of claim 1, wherein the polymeric tube comprises a fluoropolymer. 7. The device of claim 6, wherein the fluoropolymer comprises polytetrafluoroethylene (PTFE) or expanded polytetrafluoroethylene (ePTFE). 8. The device of claim 1, wherein the inflatable structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane and polyethylene. 9. The device of claim 1, wherein the inflatable structure comprises a fluoropolymer. 10. The device of claim 9, wherein the fluoropolymer comprises polytetrafluoroethylene (PTFE) or expanded polytetrafluoroethylene (ePTFE). 11. The device of claim 1, wherein the polymeric tube further comprises a reinforcement member. 12. The device of claim 11, wherein the reinforcement member is metallic. 13. The device of claim 1, wherein the inflatable structure comprises a cuff. 14. The device of claim 13, wherein the cuff is annularly disposed at the first open end of the second open end. 15. The device of claim 1, wherein the inflatable structure comprises a first cuff annularly disposed at the first open end and a second cuff annularly disposed at the second open end. 16. An endovascular system, comprising a polymeric tube having opposed open ends;an inflatable structure disposed over at least a portion of said polymeric tube;a non-inflatable expansion member disposed at one of said opposed open ends; andan inflation fluid for inflating the inflatable structure;wherein the inflatable structure is inflatable with the inflation fluid to provide an inflated state such that the inflated state conforms to the shape of a bodily lumen. 17. The system of claim 16, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. 18. The system of claim 16, wherein the inflation fluid is a gel. 19. The system of claim 18, wherein the gel hardens over time when disposed within inflatable structure. 20. The system of claim 16, further comprising a catheter for percutaneous delivery within a bodily lumen. 21. The system of claim 20, wherein the catheter further comprises an inflation balloon member. 22. The system of claim 16, wherein the polymeric tube further comprises a reinforcement member. 23. The system of claim 22, wherein the reinforcement member is metallic. 24. The system of claim 16, wherein the inflatable structure comprises a cuff. 25. The system of claim 24, wherein the cuff is annularly disposed at one of said open ends. 26. The system of claim 16, wherein the inflatable structure comprises a first cuff annularly disposed at one of said open ends and a second cuff annularly disposed at the other of said second open ends. 27. An implantable device, comprising: a frame structure of biocompatible material having first and second opposed open ends;an inflatable cuff disposed at the first open end;a non-inflatable expansion member disposed at one of said first and second opposed open ends; anda fluid for inflating the inflatable cuff. 28. The device of claim 27, wherein the inflatable cuff is inflatable with the inflation fluid to provide an inflated state such that the inflated state conforms to a shape of a bodily lumen. 29. The device of claim 27, wherein the inflatable cuff is inflatable with the inflation fluid to provide an inflated state such that the inflated state conforms to a morphology of a deployment site of the bodily lumen. 30. The device of claim 27, wherein the fluid is a gel. 31. The device of claim 30, wherein the gel hardens over time when disposed within inflatable cuff. 32. The device of claim 31, wherein the gel includes a contrast medium. 33. The device of claim 32, wherein the contrast medium includes a radiopaque material. 34. The device of claim 27, wherein the inflatable cuff has an annular shape. 35. The device of claim 15, wherein the frame structure of biocompatible material comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane, polyethylene, polyethylene terephthalate (PET) and fluoropolymer. 36. The device of claim 35, wherein the polymeric material is polyethylene terephthalate (PET). 37.
