1. A valve prosthesis system comprising:
a docking component having a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within a native heart valve, the docking component comprising: a tubular body formed from an impermeable material, the tubular body having opposing first and second end portions and an intermediate portion extending between the first and second end portions; a first annular scaffold attached to the tubular body along the first end portion thereof; a second annular scaffold attached to the tubular body along the second end portion thereof, wherein the first and second annular scaffolds are independent from each other, wherein the intermediate portion of the tubular body is unsupported such that neither of the first or second annular scaffolds surround the intermediate portion of the tubular body; and a prosthetic valve component having a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within the intermediate portion of the docking component, wherein the prosthetic valve component is configured to be delivered separately from the docking component. |
