Abstract
An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

1-27. (canceled)
A retrievable transcatheter cardiovascular prosthetic aortic heart valve comprising:
- an expandable carrier element having a distal end furthest from a delivery catheter during insertion and a proximal end closest to the delivery catheter during insertion, the expandable carrier element having a delivery configuration when the expandable carrier element is collapsed inside the delivery catheter, and an expanded configuration;
- and
- a prosthetic valve coupled to the flexible carrier element between the proximal end of the flexible carrier element and a distal end of the flexible carrier element, the prosthetic valve configured to replace the function of a native aortic heart valve in the expanded configuration,
- wherein the prosthetic valve is configured to prevent the flow of blood through the prosthetic valve in a first direction and allow the flow of blood through the prosthetic valve in a second direction during the expansion of the flexible carrier element from the delivery configuration to the expanded configuration, and after expanding the distal end of the expandable carrier element prior to expanding the proximal end of the expandable carrier element.
