Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
96 words
An annuloplasty band for repair of an atrio-ventricular valve forming a valve annulus, the band comprising: a sheath; and a generally arcuate stiffening element entirely 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; wherein upon assembly, a maximum transverse width of the sheath at the first and second end eyelets is greater than a maximum transverse width of a remainder of the sheath.
Claim 2
Dependent Claim
96 words
An annuloplasty band for repair of an atrio-ventricular valve forming a valve annulus, the band comprising: a sheath; and a generally arcuate stiffening element entirely 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; wherein upon assembly, a maximum transverse width of the sheath at the first and second end eyelets is greater than a maximum transverse width of a remainder of the sheath.
Claim 3
Dependent Claim
66 words
The annuloplasty band of claim 1 , wherein the valve is a mitral valve having an antero-lateral trigone, a posterior leaflet, and a postero-medial trigone; wherein the arcuate shape of the band generally conforms to an expected natural shape of the valve annulus; and further wherein the eyelets are adapted to secure the annuloplasty band to the intero-lateral trigone and the postero-medial trigone, respectively, via sutures.
Claim 4
Dependent Claim
85 words
The annuloplasty band of claim 1 , wherein the valve is a tricuspid valve having an anterior leaflet, a posterior leaflet and a septal leaflet, each of the leaflets defined by a base relative to the valve annulus; wherein the arcuate shape of the band generally conforms to an expected natural shape of the valve annulus; and further wherein the eyelets are adapted to secure the annuloplasty band to the base of the septal leaflet and the base of the anterior leaflet, respectively, via sutures.
Claim 5
Dependent Claim
25 words
The annuloplasty band of claim 1 , wherein the stiffening element includes a wire having opposite ends bent back onto itself to form the eyelets.
Claim 6
Dependent Claim
16 words
The annuloplasty band of claim 4 , wherein the wire is overmolded with an elastomeric material.
Claim 7
Dependent Claim
26 words
The annuloplasty band of claim 5 , wherein the elastomeric material includes a material selected from the group consisting of biocompatible thermal plastic elastomer and silicone.
Claim 8
Dependent Claim
52 words
The annuloplasty band of claim 4 , wherein the wire is configured to define a compound curve including an intermediate portion having a first radius of curvature and opposite end portions each having a second radius of curvature, wherein the first radius of curvature is greater than the second radius of curvature.
Claim 9
Dependent Claim
63 words
The annuloplasty band of claim 7 , wherein each of the end portions includes: a transition segment extending outwardly from the intermediate portion, the transition segment having the second radius of curvature; an end segment extending from the transition segment, the end segment having a third radius of curvature; wherein the second radius of curvature is greater than the third radius of curvature.
Claim 10
Dependent Claim
16 words
The annuloplasty band of claim 1 , wherein the stiffening element includes a molded polymeric element.
Claim 11
Dependent Claim
40 words
The annuloplasty band of claim 1 , wherein the sheath is discretely marked at a first location corresponding to a position of the first end eyelet and at a second location corresponding to a position of the second end eyelet.
Claim 12
Dependent Claim
29 words
The annuloplasty band of claim 10 , wherein the sheath is marked to indicate eyelet placement by a suture having a color different from a color of the sheath.
Claim 13
Dependent Claim
13 words
The annuloplasty band of claim 1 , wherein the stiffening element is radio-opaque.
Claim 14
Dependent Claim
16 words
The annuloplasty band of claim 1 , wherein the sheath is formed of a fabric material.
Claim 15
Dependent Claim
15 words
The annuloplasty band of claim 1 , wherein the sheath is formed of biological tissue.
Claim 16
Dependent Claim
19 words
The annuloplasty band of claim 1 , wherein the band has a thickness no greater than approximately 3 mm.
Claim 17
Dependent Claim
31 words
The annuloplasty band of claim 1 , wherein the stiffening element is configured to independently maintain a generally arcuate shape in an X-Y plane and a generally saddle-shape in a Z-plane.
