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. ## Claims ### Claim 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; and a 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. ### Claim 2 (depends on 1) The device of claim 1, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 3) The device of claim 3, wherein the fluoropolymer is selected from the group consisting of polytetrafluoroethylene (PTFE) and expanded polytetrafluoroethylene (ePTFE). ### Claim 5 (depends on 1) The device of claim 1, wherein the inflatable structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane and polyethylene. ### Claim 6 (depends on 1) The device of claim 1, wherein the inflatable structure comprises a polyurethane material. ### Claim 7 (depends on 1) The device of claim 1, wherein the non-inflatable expansion member is configured to self-expand from a constrained state. ### Claim 8 (depends on 1) The device of claim 1, wherein the non-inflatable expansion member is configured expand to upon application of an outward radial force. ### Claim 9 (depends on 8) The device of claim 8, wherein the application of the outward radial force is provided by an inflation member of a balloon catheter. ### Claim 10 (depends on 1) A system for percutaneous delivery of an implantable device, comprising: the implantable device of claim 1; and a delivery catheter. ### Claim 11 (depends on 1) The device of claim 1, wherein the non-inflatable expansion member comprises an expandable ring having a serpentine configuration. ### Claim 12 (depends on 11) 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. ### Claim 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; and a 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; and 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. ### Claim 14 (depends on 13) The device of claim 13, wherein the inflated state conforms to a morphology of a deployment site of a bodily lumen. ### Claim 15 (depends on 13) 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. ### Claim 16 (depends on 15) The device of claim 15, wherein the fluoropolymer is selected from the group consisting of polytetrafluoroethylene (PTFE) and expanded polytetrafluoroethylene (ePTFE). ### Claim 17 (depends on 13) The device of claim 13, wherein the inflatable structure comprises a polymeric material selected from the group consisting of polyvinylchloride (PVC), polyurethane and polyethylene. ### Claim 18 (depends on 13) The device of claim 13, wherein the inflatable structure comprises a polyurethane material. ### Claim 19 (depends on 13) A system for percutaneous delivery of an implantable device, comprising: the implantable device of claim 13; and a delivery catheter.
