1. An annuloplasty prosthesis comprising:
- an elongated structural member that is curved along its length to correspond to a portion of a cardiac valve annulus, the structural member including first and second surface portions that are transverse to adjacent portions of the surface of the structural member and that are spaced from and face toward one another along the length of the structural member.

Abstract
An annuloplasty prosthesis is less than a complete ring (e.g., it may be C-shaped or U-shaped). The prosthesis has a structural member that basically gives the prosthesis its shape. The structural member is provided with surface portions that are transverse to adjacent portions of the surface of the structural member. At least two of these transverse surface portions are spaced from one another and face toward one another along the length of the structural member. Sutures that are used to implant the prosthesis and that are respectively adjacent to these two transverse surface portions are thereby prevented from moving farther apart along the length of the prosthesis.

17. An annuloplasty method comprising:
-
providing an annuloplasty prosthesis that includes an elongated structural member that is curved along its length to correspond to a portion of a cardiac valve annulus, the structural member including first and second surface portions that are transverse to adjacent portions of the surface of the structural member and that are spaced from and face toward one another along the length of the structural member;
implanting the prosthesis so that the structural member is adjacent and generally parallel to the portion of the cardiac valve annulus; and
suturing the prosthesis to adjacent tissue, with at least some sutures used in the suturing being respectively adjacent the first and second surface portions so that the first and second surface portions resist movement of those sutures farther away from one another along the length of the structural member. - View Dependent Claims (18, 19, 20)
