Annuloplasty band and method
First Claim
1. A method of implanting an annuloplasty band for repairing an atrio-ventricular valve defining a valve annulus, the method comprising:
- providing an annuloplasty band including a sheath and a generally arcuate stiffening element disposed within the sheath, the stiffening element extending from a first end to a second end and defining a compound curve shape between the first and second ends so as to mimic at least a portion of a natural valve annulus, each end forming an eyelet adapted to receive a suture;
positioning the annuloplasty band along at least a portion of the valve annulus; and
suturing the respective eyelets to tissue of the valve annulus and further suturing the annuloplasty band between the first and second ends thereof to tissue of the valve annulus for shaping the valve annulus based upon the shape of the stiffening element.

Abstract
An annuloplasty band comprising a sheath, and a generally arcuate stiffening element disposed within the sheath. The stiffening element extends from a first end to a second end, and preferably includes eyelets at its first and second ends adapted to receive sutures to secure the annuloplasty band to a valve annulus. The annuloplasty band preferably has a low profile (e.g., a thickness less than 3 mm). In embodiments intended for mitral valve repair, the eyelets are particularly adapted to receive sutures to secure the annuloplasty band to the antero-lateral trigone and postero-medial trigone. A holder and sizer device useful with the annuloplasty band are also provided.

5. A method of implanting an annuloplasty ring for repairing a mitral valve defining a valve annulus having a posterior annulus portion and an anterior annulus portion, the method comprising:
-
providing an annuloplasty ring comprising a polyester sheath, a generally arcuate, non-planar stiffening element disposed within the polyester sheath, the stiffening element comprising titanium and having a compound curve shape along at least a posterior portion thereof that is adapted to extend along the posterior annulus portion of the mitral valve annulus, wherein the non-planar stiffening element comprises a saddle shape to mimic a natural mitral valve annulus; positioning the annuloplasty ring along the valve annulus; and suturing the ring to tissue of the valve annulus for shaping the valve annulus based upon the saddle shape of the stiffening element. - View Dependent Claims (6, 7)

-
providing an annuloplasty ring comprising a polyester sheath, a generally arcuate, non-planar stiffening element disposed within the polyester sheath, the stiffening element comprising titanium and having a compound curve shape along at least a posterior portion thereof that is adapted to extend along the posterior annulus portion of the mitral valve annulus, wherein the ring comprises a continuous saddle shape; associating a holder with the annuloplasty ring; positioning the annuloplasty ring and associated holder along the valve annulus; and suturing the ring to tissue of the valve annulus for shaping the valve annulus based upon the saddle shape of the stiffening element; and disassociating the holder from the ring. - View Dependent Claims (9, 10, 11, 12, 13)
