Abstract
An annuloplasty ring for repairing a cardiac valve includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion between the end portions. The proximal end portion of the support member includes a plurality of wing members that extend from the main body portion. Each of the wing members includes at least one hook member for embedding into a cardiac wall and the valve annulus to secure the annuloplasty ring in the valve annulus. The annuloplasty ring may be expanded into full contact engagement with the annulus of the cardiac valve by an inflatable balloon. Methods for repairing a cardiac valve using the annuloplasty ring are also provided.
