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 implantable device, comprising: a frame structure of biocompatible graft material having first and second opposed open ends, said first opposed open end having a longitudinal axis and a neck portion disposed directly at a terminal portion of said first opposed open end;a non-inflatable expansi
1. An implantable device, comprising: a frame structure of biocompatible graft material having first and second opposed open ends, said first opposed open end having a longitudinal axis and a neck portion disposed directly at a terminal portion of said first opposed open end;a non-inflatable expansion member generally coextensive with the longitudinal axis of said first opposed open end and securably disposed at the neck portion of said frame structure;an inflatable structure disposed over at least a first portion of said frame structure near said first opposed open end, wherein the inflatable structure is longitudinally spaced apart from the non-inflatable expansion member; anda 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. 2. The device of claim 1, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. 3. The device of claim 1, wherein the biocompatible graft material of the frame structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane, polyethylene, polyethylene terephthalate (PET) and fluoropolymer. 4. The device of claim 3, wherein the fluoropolymer is selected from the group consisting of polytetrafluoroethylene (PTFE) and expanded polytetrafluoroethylene (ePTFE). 5. The device of claim 1, wherein the inflatable structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane and polyethylene. 6. The device of claim 1, wherein the inflatable structure comprises a polyurethane material. 7. The device of claim 1, wherein the non-inflatable expansion member is configured to self-expand from a constrained state. 8. The device of claim 1, wherein the non-inflatable expansion member is configured expand to upon application of an outward radial force. 9. The device of claim 8, wherein the application of the outward radial force is provided by an inflation member of a balloon catheter. 10. A system for percutaneous delivery of an implantable device, comprising: the implantable device of claim 1; anda delivery catheter. 11. The device of claim 1, wherein the non-inflatable expansion member comprises an expandable ring having a serpentine configuration. 12. The device of claim 11, wherein a portion of the serpentine configuration of the non-inflatable expansion member is disposed beyond said first opposed open end of the frame structure. 13. An implantable device, comprising: a frame structure comprising biocompatible graft material having first and second opposed open ends and a metallic reinforcement member, said first opposed open end having a longitudinal axis and a neck portion disposed directly at a terminal portion of said first opposed open end;an inflatable structure disposed over at least a first portion of said frame structure near said first opposed open end; anda fluid for inflating the inflatable structure;wherein the metallic reinforcement member is securably disposed at the neck portion of said frame structure, the metallic reinforcement member being longitudinally spaced apart from the inflatable structure; andwherein 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. 14. The device of claim 13, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. 15. The device of claim 13 wherein the biocompatible graft material of the frame structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane, polyethylene, polyethylene terephthalate (PET) and fluoropolymer. 16. The device of claim 15, wherein the fluoropolymer is selected from the group consisting of polytetrafluoroethylene (PTFE) and expanded polytetrafluoroethylene (ePTFE). 17. The device of claim 13, wherein the inflatable structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane and polyethylene. 18. The device of claim 13, wherein the inflatable structure comprises a polyurethane material. 19. A system for percutaneous delivery of an implantable device, comprising: the implantable device of claim 13; anda delivery catheter.
