Abstract
A percutaneous heart valve assembly includes a gasket member or other first prosthesis and a valve member or other second prosthesis. The first and second prostheses are contractible from an enlarged or relaxed condition into a contracted or delivery condition. The prostheses may be loaded into the same or separate catheters or other delivery devices for delivery through a patient's vasculature to an implantation site, e.g., a biological annulus within a heart. The first prosthesis may be deployed adjacent or within the biological annulus and secured at least partially into the biological annulus. The second prosthesis may then be deployed adjacent the biological annulus, expanded, and docked to the first prosthesis. In one embodiment, the first and/or second prostheses may be advanced over one or more sutures or other filaments secured to tissue surrounding or adjacent the biological annulus.
