Annuloplasty band and method
First Claim
1. An annuloplasty band for repair of an atrio-ventricular valve forming a valve annulus, the band comprising:
- a sheath;
a generally arcuate stiffening element disposed within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends includes an eyelet adapted to receive a suture for securing the annuloplasty band to the valve annulus.

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.

17. 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, each end forming an eyelet adapted to receive a suture;
positioning the annuloplasty band along the valve annulus; and
suturing the respective eyelets to tissue of the valve annulus. - View Dependent Claims (18, 19, 20)

21. A combination annuloplasty band and holder for use by a surgeon in conjunction with annuloplasty surgery performed on a patient'"'"'s heart valve defining a valve annulus, comprising:
-
an annuloplasty band comprising a sheath and a generally arcuate stiffening element disposed within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends forms an eyelet adapted to receive a suture for securing the annuloplasty band to the valve annulus; and
a holder selectively maintaining the annuloplasty band, the holder including a band-retaining plate forming a perimeter defining a curvature corresponding generally with a curvature of the annuloplasty band, the perimeter further forming cut-out areas adapted to provide clearance about the eyelets upon mounting of the annuloplasty band to the band-retaining plate. - View Dependent Claims (22, 23, 24, 25, 26)

27. A holder for an annuloplasty band including a band-retaining plate forming a perimeter defining:
-
an arcuate segment;
opposing cut-out regions extending from opposite sides of the arcuate segment, respectively; and
a trailing segment extending between the opposing cut-out regions opposite the arcuate segment;
wherein the opposing cut-out regions each define a transition from the arcuate segment to the trailing segment, the cut-out regions each having a first portion extending inwardly from the arcuate segment and a second portion extending outwardly from the first portion to the trailing segment. - View Dependent Claims (28, 29)

34. A sizer device for use in evaluating a size of an atrio-ventricular valve annulus as part of a valve repair procedure, the sizer device including a sizer forming a perimeter defining:
-
a leading segment shaped in accordance with a portion of a shape of a natural atrio-ventricular valve annulus;
a trailing segment opposite the leading segment, and opposing cut-out segments located at opposite sides of the leading segment, respectively, wherein the opposing cut-out segments are adapted to facilitate viewing of portions of the valve annulus upon placement of the sizer into close proximity to the valve annulus. - View Dependent Claims (35, 36)

a holder including a band-retaining plate forming a perimeter defining a curvature corresponding generally with a curvature of the annuloplasty band;
a first suture looping about the first end of the annuloplasty band and holding the first end of the annuloplasty band against the band-retaining plate; and
a second suture looping about the second end of the annuloplasty band and holding the second end of the annuloplasty band against the band-retaining plate. - View Dependent Claims (38, 39, 40)
