Valve prosthesis including a prosthetic leaflet
First Claim
1. A valve prosthesis, comprising:
- (a) a frame, said frame comprising a first portion extending longitudinally through an annular arc; and
, (b) a substantially undeflectable leaflet extending downwardly from said first portion, said leaflet including a prosthetic surface extending below and offset radially inwardly from said first portion.

Abstract
A prosthesis for repairing a damaged valve such as a heart mitral valve is disclosed. The prothesis comprises a prosthetic valve leaflet mounted on a frame. When implanted in a mitral valve, the leaflet replaces the function of an endogenous valve leaflet and coapts with an opposed endogenous valve leaflet. The prosthesis may further comprise a strut or other member to which the edge of an opposed valve leaflet can be sutured, and which can be used to correct deformities of a ventricle wall. Further disclosed is a method of repairing a damaged heart valve by providing a prosthetic valve leaflet or by providing a prosthetic valve leaflet and prosthetic attachment points for an opposed valve leaflet.
