Claim:
1. A transcatheter valve prosthesis, the prosthesis comprising: a tubular fabric body formed from a synthetic material, the tubular fabric body having opposing first and second end portions and an intermediate portion extending between the first and second end portions, wherein the tubular fabric body defines a lumen there-through; a first tubular scaffold attached to the tubular fabric body along the first end portion thereof; a second tubular scaffold attached to the tubular fabric body along the second end portion thereof, wherein the first and second tubular scaffolds are independent from each other; a prosthetic valve component disposed within and secured to the intermediate portion of the tubular fabric body, the prosthetic valve component being configured to block blood flow in one direction to regulate blood flow through the lumen of the tubular fabric body, wherein the prosthetic valve component includes at least two leaflets and wherein the intermediate portion of the tubular fabric body is unsupported such that no tubular scaffolds surround the intermediate portion of the tubular fabric body and the intermediate portion of the tubular fabric body has no radial support along its length or circumference; and at least two reinforcement members that are attached to the intermediate portion of the tubular fabric body, the at least two reinforcement members being aligned with commissures of the at least two leaflets of the prosthetic valve component and the at least two reinforcement members being only attached to the intermediate portion of the tubular fabric body and not attached to the first tubular scaffold or the second tubular scaffold, wherein the prosthesis has a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within a native valve.
