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: 12
Claim 1
Independent Claim
137 words
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 entirely within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends of the stiffening element 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.
Claim 2
Dependent Claim
137 words
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 entirely within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends of the stiffening element 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.
Claim 3
Dependent Claim
33 words
The combination of claim 1 , wherein: the stiffening element comprises a wire having opposite ends bent back onto itself to form the eyelets; and the wire is overmolded with an elastomeric material.
Claim 4
Dependent Claim
15 words
The combination of claim 1 , wherein the sheath is marked to indicate eyelet placement.
Claim 5
Dependent Claim
28 words
The combination of claim 3 , wherein the sheath is marked to indicate eyelet placement by a suture having a color contrasting with a color of the sheath.
Claim 6
Dependent Claim
21 words
The combination of claim 1 , wherein the annuloplasty band and the band-retaining plate are adapted for repairing a mitral valve.
Claim 7
Dependent Claim
21 words
The combination of claim 1 , wherein the annuloplasty band and the band-retaining plate are adapted for repairing a tricuspid valve.
Claim 8
Dependent Claim
157 words
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 entirely within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends of the stiffening element forms an eyelet adapted to receive a suture for securing the annuloplasty band to the valve annulus; 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.
Claim 9
Dependent Claim
157 words
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 entirely within the sheath, the stiffening element extending from a first end to a second end, wherein each of the first and second ends of the stiffening element forms an eyelet adapted to receive a suture for securing the annuloplasty band to the valve annulus; 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.
Claim 10
Dependent Claim
25 words
The combination of claim 7 , also comprising fingers on the retaining plate holding a central portion of the annuloplasty band against the band-retaining plate.
Claim 11
Dependent Claim
42 words
The combination of claim 7 also comprising a first cut point for releasing the first suture from the first end of the annuloplasty band and a second cut point for releasing the second suture from the second end of the annuloplasty band.
Claim 12
Dependent Claim
19 words
The combination of claim 7 , wherein the first suture and second suture do not penetrate the annuloplasty band.
