TWO-PIECE PERCUTANEOUS PROSTHETIC HEART VALVES AND METHODS FOR MAKING AND USING THEM
First Claim
1. A system for delivering a multiple component prosthetic valve into a biological annulus within a patient'"'"'s body, comprising:
- an elongate tubular member comprising a proximal end, a distal end sized for introduction into a body lumen, and a lumen extending between the proximal and distal ends;
a first annular prosthesis implantable within the biological annulus, the annular prosthesis being disposed within the tubular member adjacent the distal end in a contracted condition, the annular prosthesis being expandable upon deployment from the tubular member within the biological annulus to an enlarged condition; and
a second valve prosthesis securable to the annular prosthesis, the valve prosthesis being disposed within the tubular member adjacent the annular prosthesis in a contracted condition, the valve prosthesis being expandable upon deployment from the tubular member within the biological annulus such that the valve prosthesis may be secured to the annular prosthesis.

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.
