PROSTHETIC VALVE SYSTEM HAVING A DOCKING COMPONENT AND A PROSTHETIC VALVE COMPONENT
First Claim
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.

Abstract
A two-component valve prosthesis system includes a docking component and a prosthetic valve component that is configured to be delivered separately from the docking component. The docking component has a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The docking component includes a tubular skirt, a first annular scaffold attached to a first end of the tubular skirt and a second annular scaffold attached to a second end of the tubular skirt. The first and second annular scaffolds are independent from each other. An intermediate portion of the tubular skirt is unsupported such that neither of the first or second annular scaffolds surrounds the intermediate portion of the tubular skirt. The prosthetic valve component has a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within the intermediate portion of the docking component.

8. A valve prosthesis system, the system comprising:
-
an exterior docking component including a tubular skirt, a first annular scaffold attached to a first end of the tubular skirt, and a second annular scaffold attached to a second end of the tubular skirt, the exterior docking component having a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within a native heart valve, wherein the first and second annular scaffolds are independent from each other and an intermediate portion of the tubular skirt that longitudinally extends between the first and second annular scaffolds is unsupported such that neither of the first or second annular scaffolds surround the intermediate portion of the tubular skirt; an interior dockable component including an scaffold and at least two valve leaflets disposed within and secured to the scaffold, the interior dockable component having a compressed configuration for percutaneous delivery within a vasculature and an expanded configuration for deployment within the skirt of the exterior docking component, wherein the interior dockable component is configured to be delivered separately from the exterior docking component and the interior dockable component is configured to couple to the intermediate portion of the tubular skirt of the exterior docking component in situ such that the tubular skirt is radially disposed around and contacts the interior dockable component. - View Dependent Claims (9, 10, 11, 12)

13. A method of implanting a valve prosthesis system within a native valve, the method comprising the steps of:
-
percutaneously advancing a docking component to a native valve, wherein the docking component is in a compressed configuration during delivery and wherein the docking component includes a tubular body formed from an impermeable material, a first annular scaffold attached to the tubular body along a first end portion thereof, and a second annular scaffold attached to the tubular body along a second end portion thereof, the first and second annular scaffolds being independent from each other and an intermediate portion of the tubular body being unsupported such that neither of the first or second annular scaffolds surround the intermediate portion of the tubular body; and deploying the docking component to an expanded configuration within the native valve; percutaneously delivering a prosthetic valve component within a vasculature to the native heart valve, wherein the prosthetic valve component is in a compressed configuration during delivery; and deploying the prosthetic valve component to an expanded configuration within the intermediate portion of the docking component, wherein deployment of the prosthetic valve component occurs after deployment of the docking component. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
