Abstract
Abstract An annuloplasty ring includes an elongated main body having a generally partial shape extending between first and second ends. An elongated secondary body also includes first and second ends which couple to, respectively, the first and second ends of the main body. A first cut zone couples the first end of the main body to the first end of the secondary body. A second cut zone couples the second end of the main body to the second end of the secondary body. The annuloplasty ring may be selectively formed generally into a partial annuloplasty ring shape by severing the first and second cut zones and removing the secondary body.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
177 words
An annuloplasty ring, comprising: an elongated main body portion having a generally partial annuloplasty shape extending between a first end and a second end, the main body made of a biocompatible material; an elongated secondary body portion having a first end and a second end extending between, respectively, the first and the second ends of the elongated main body portion, the secondary body portion made of a cutable coreless biocompatible fabric material and fabricated to allow cutting therein without fraying of the secondary body; and a first cut zone marker which couples the first end of the main body portion to the first end of the secondary body portion; a second cut zone marker which couples the second end of the main body portion to the second end of the secondary body portion; wherein at least a portion of the secondary body portion is selectively removable by severing at any two locations between the first cut zone marker and the second cut zone marker, thereby forming a non-fraying annuloplasty ring having a generally partial annuloplasty ring shape.
Claim 2
Dependent Claim
177 words
An annuloplasty ring, comprising: an elongated main body portion having a generally partial annuloplasty shape extending between a first end and a second end, the main body made of a biocompatible material; an elongated secondary body portion having a first end and a second end extending between, respectively, the first and the second ends of the elongated main body portion, the secondary body portion made of a cutable coreless biocompatible fabric material and fabricated to allow cutting therein without fraying of the secondary body; and a first cut zone marker which couples the first end of the main body portion to the first end of the secondary body portion; a second cut zone marker which couples the second end of the main body portion to the second end of the secondary body portion; wherein at least a portion of the secondary body portion is selectively removable by severing at any two locations between the first cut zone marker and the second cut zone marker, thereby forming a non-fraying annuloplasty ring having a generally partial annuloplasty ring shape.
Claim 3
Dependent Claim
34 words
The annuloplasty ring of claim 1 wherein the secondary body includes a body retaining member to maintain integrity of the first end of the main body portion when the first cut zone is severed.
Claim 4
Dependent Claim
27 words
The annuloplasty ring of claim 2 wherein the main body portion includes a fabric layer and the body retaining member substantially prevents fraying of the fabric layer.
Claim 5
Dependent Claim
14 words
The annuloplasty ring of claim 2 wherein the body retaining member comprises a suture.
Claim 6
Dependent Claim
11 words
The annuloplasty ring of claim 4 wherein the suture is knotted.
Claim 7
Dependent Claim
27 words
The annuloplasty ring of claim 5 wherein the knotted suture forms a visual pattern to mark the first cut zone marker and the second cut zone marker.
Claim 8
Dependent Claim
15 words
The annuloplasty ring of claim 1 wherein the elongated main body portion includes a core.
Claim 9
Dependent Claim
24 words
The annuloplasty ring of claim 7 wherein the core does not extend between the first cut zone marker and the second cut zone marker.
Claim 10
Dependent Claim
15 words
The annuloplasty ring of claim 1 wherein the main body comprises a substantially flexible material.
Claim 11
Dependent Claim
94 words
An annuloplasty prosthesis, comprising: an annuloplasty ring including a main body and a secondary body, the secondary body formed of a cutable coreless biocompatible fabric material, wherein a portion of the annuloplasty ring may be selectively severed in a cut zone region to form a non-fraying partial annuloplasty ring shape; first and second markers which provide a visual indication of the location of the cut zone; and a suture extending through the material in the cut zone region and having a plurality of knots to prevent fraying if the cut zone region is severed.
Claim 12
Dependent Claim
94 words
An annuloplasty prosthesis, comprising: an annuloplasty ring including a main body and a secondary body, the secondary body formed of a cutable coreless biocompatible fabric material, wherein a portion of the annuloplasty ring may be selectively severed in a cut zone region to form a non-fraying partial annuloplasty ring shape; first and second markers which provide a visual indication of the location of the cut zone; and a suture extending through the material in the cut zone region and having a plurality of knots to prevent fraying if the cut zone region is severed.
Claim 13
Dependent Claim
24 words
The annuloplasty prosthesis of claim 10 wherein the plurality of knots include elongated stitches which are visible to thereby mark the cut zone region.
Claim 14
Dependent Claim
18 words
The annuloplasty prosthesis of claim 10 including an annular core extending at least partially through the annuloplasty ring.
Claim 15
Dependent Claim
