APPARATUS AND METHODS FOR REPAIR OF A CARDIAC VALVE
First Claim
1. An apparatus for repairing a cardiac valve, said apparatus comprising:
- an annuloplasty ring including an expandable support member having oppositely disposed proximal and distal end portions and a main body portion between said end portions, said proximal end portion of said expandable support member comprising a plurality of wing members that extend from said main body portion;
each of said wing members including at least one hook member for embedding into a cardiac wall and the valve annulus to secure said annuloplasty ring in the annulus of the cardiac valve; and
an energy delivery mechanism for selectively contracting said annuloplasty ring and thereby restricting the valve annulus to support the annulus and correct valvular insufficiency, said energy delivery mechanism including a detachable electrical lead having distal and proximal end portions, said distal end portion having a securing member for operably attaching said distal end portion to a portion of said expandable support member and said proximal end portion being operably connected to an energy delivery source.

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.
