Abstract
Abstract A support ring for a natural human heart valve includes a first ring portion having opposite terminal ends and a second ring portion having opposite terminal ends. An interconnector extends through and interconnects the first and second ring portions, to maintain the opposite terminal ends of the first ring portion adjacent the opposite terminal ends of the second ring portion, to form a segmented ring having a first and a second interface between the first and second ring portions. The first ring portion is of a greater length than the second ring portion. The ring portions are separable by severing the interconnector at the first and second interfaces, thus producing two variable size ring segments.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
69 words
A separable annuloplasty ring comprising: a first ring portion comprising a first tube member; a second ring portion comprising a second tube member; an interconnector member coupling the First and the second ring portions, said interconnector member extending through said first tube member and said second tube member, said annuloplasty ring being separable by severing said interconnector member without severing said first ring portion or said second ring portion.
Claim 2
Dependent Claim
69 words
A separable annuloplasty ring comprising: a first ring portion comprising a first tube member; a second ring portion comprising a second tube member; an interconnector member coupling the First and the second ring portions, said interconnector member extending through said first tube member and said second tube member, said annuloplasty ring being separable by severing said interconnector member without severing said first ring portion or said second ring portion.
Claim 3
Dependent Claim
40 words
The separable ring of claim 1 wherein the first ring portion further comprises a first outer covering and first and second terminal ends, and the second ring portion further comprises a second outer covering and first and second terminal ends.
Claim 4
Dependent Claim
32 words
The ring as defined in claim 1 wherein the first ring portion is of a first length and the second ring portion is of a second length, greater than the first length.
Claim 5
Dependent Claim
62 words
The separable ring of claim 1 wherein the first ring portion further comprises first and second terminal ends and the second ring portion further comprises first and second terminal ends, and wherein the first and second terminal ends of said first ring portion are coupled to the first and second terminal ends, respectively, of the second ring portion by the interconnector member.
Claim 6
Dependent Claim
43 words
The ring of claim 4 wherein the interconnector member is exposed sufficiently between said coupled first terminal ends and second terminal ends of said first and second ring portions for being severed without severing said first ring portion or said second ring portion.
Claim 7
Dependent Claim
32 words
The ring as defined in claim 5 wherein the first ring portion is of a first length and the second ring portion is of a second length, greater than the first length.
Claim 8
Dependent Claim
33 words
The ring of claim 2 wherein the first tube member and the second tube member each comprise a silicone tube and said first and second outer coverings each comprise a polyester knit tube.
Claim 9
Dependent Claim
95 words
A cardiac valvular prosthesis for a heart valve comprising: a segmented ring having a first ring segment comprising a first tube member having first and second terminal ends, and a second ring segment comprising a second tube member having first and second terminal ends, terminal ends of the first tube member being coupled to terminal ends of the second tube member by an interconnector member extending through and interconnecting the first and second tube members, the interconnector having a first connection to the first tube member and a second connection to the second tube member.
Claim 10
Dependent Claim
95 words
A cardiac valvular prosthesis for a heart valve comprising: a segmented ring having a first ring segment comprising a first tube member having first and second terminal ends, and a second ring segment comprising a second tube member having first and second terminal ends, terminal ends of the first tube member being coupled to terminal ends of the second tube member by an interconnector member extending through and interconnecting the first and second tube members, the interconnector having a first connection to the first tube member and a second connection to the second tube member.
Claim 11
Dependent Claim
39 words
The prosthesis as defined in claim 8 wherein the interconnector is exposed sufficiently for being severed between said coupled terminal ends of said first and second tube members without severing said first ring segment or said second ring segment.
Claim 12
Dependent Claim
30 words
The prothesis as defined in claim 9 wherein the first ring segment and the length and the second ring segment is of a second length, greater than the first length.
Claim 13
Dependent Claim
24 words
The prosthesis of claim 8 wherein the first tube member and the second tube member each comprise a silicone tube within a polyester tube.
Claim 14
Dependent Claim
22 words
The prothesis as defined in claim 11 wherein the interconnector extends through the silicone tube of the first and second ring segments.
Claim 15
Dependent Claim
106 words
A support ring for a natural human heart valve comprising: a first ring portion comprising a first tube member and having opposite terminal ends; a second ring portion comprising a second tube member and having opposite terminal ends; and an interconnector member extending through said first tube member and said second tube member, said interconnector coupling the first and the second ring portions and maintaining the opposite terminal ends of the first ring portion adjacent the opposite terminal ends of the second ring portion to form a segmented ring separable by severing said interconnector member without severing said first ring portion or said second ring portion.
Claim 16
Dependent Claim
106 words
A support ring for a natural human heart valve comprising: a first ring portion comprising a first tube member and having opposite terminal ends; a second ring portion comprising a second tube member and having opposite terminal ends; and an interconnector member extending through said first tube member and said second tube member, said interconnector coupling the first and the second ring portions and maintaining the opposite terminal ends of the first ring portion adjacent the opposite terminal ends of the second ring portion to form a segmented ring separable by severing said interconnector member without severing said first ring portion or said second ring portion.
