Nonstented heart valves with formed in situ support
First Claim
1. A method of in situ formation of a prosthetic valve support at a site of a native valve, comprising the steps of:
- providing a prosthetic valve, attached to a flexible support component which is incapable of retaining the prosthetic valve at a functional site in the arterial vasculature, the support component extending both proximally and distally of the base of the native valve;
positioning the prosthetic valve at the site such that the flexible support component spans the site of the native valve; and
supplementing the flexible support component to increase the rigidity of the support component sufficiently to retain the prosthetic valve at the site.

Abstract
An implantable prosthetic valve having an in situ formable support structure and methods of deploying such a valve are disclosed. In one arrangement, the valve has a base and at least one flow occluder. A first flexible component which is incapable of retaining the valve at a functional site in the arterial vasculature extends proximally of the base of the valve. A second flexible component which is incapable of retaining the valve at a functional site in the arterial vasculature 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.

18. A method of in situ formation of a prosthetic valve support at a site of a native valve, comprising the steps of:
-
providing a prosthetic valve, attached to a flexible support component which is incapable of retaining the valve at a functional site in the arterial vasculature, the support component extending both proximally and distally of the base of the native valve; positioning the valve at the site such that the flexible support component spans the native valve; and supplementing the flexible support component to increase the rigidity of the support component sufficiently to retain the valve at the site, wherein the supplementing step comprises introducing inflation media into the support component, and increasing the viscosity of the inflation media following introduction into the support component. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
