ABSTRACT:
An apparatus for repairing a cardiac valve includes an annuloplasty ring having an expandable support member with oppositely disposed proximal and distal end portions and a main body portion between the end portions. The proximal end portion includes a plurality of wing members extending from the main body portion. Each of the wing members includes at least one hook member for embedding into a cardiac wall and a valve annulus to secure the annuloplasty ring therein. The apparatus also includes an energy delivery mechanism for selectively contracting the annuloplasty ring to restrict the valve annulus and correct valvular insufficiency. The energy delivery mechanism includes a detachable electrical lead having distal and proximal end portions. The distal end portion has a securing member for operably attaching the distal end portion to a portion of the expandable support member. The proximal end portion is operably connected to an energy delivery source.
