Abstract
Abstract The resilient self molding annuloplasty ring which may be enlarged prior to implantation to facilitate implantation within a dilated or otherwise incompetent valve annulus having sufficient contractive force to render a valve competent. The self molding annuloplasty ring of the invention may further comprise integral attachment devices to aid in the implantation process. The invention further discloses an illustrative method of implantation.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
96 words
A sizable self-molding annuloplasty ring for implantation in a heart valve annulus, comprising: a resilient inner sizing member; a plurality of support members positioned on said inner sizing member; and, an outer attachment sheath enclosing said sizing member and said support members; wherein the inner sizing member is biased toward a fully relaxed diameter but can be stretched to a fully expanded diameter; and wherein the plurality of support members constrain contraction of the inner sizing member to a contracted diameter that is larger than the fully relaxed diameter but smaller than the fully expanded diameter.
Claim 2
Dependent Claim
96 words
A sizable self-molding annuloplasty ring for implantation in a heart valve annulus, comprising: a resilient inner sizing member; a plurality of support members positioned on said inner sizing member; and, an outer attachment sheath enclosing said sizing member and said support members; wherein the inner sizing member is biased toward a fully relaxed diameter but can be stretched to a fully expanded diameter; and wherein the plurality of support members constrain contraction of the inner sizing member to a contracted diameter that is larger than the fully relaxed diameter but smaller than the fully expanded diameter.
Claim 3
Dependent Claim
29 words

Claim 7
Dependent Claim
19 words
The annuloplasty ring of claim 1 wherein said annuloplasty ring further comprises a plurality of attachment devices positioned thereon.
Claim 8
Dependent Claim
21 words
The annuloplasty ring of claim 6 wherein said attachment devices are selected from the group consisting of: needles; barbs; and hooks.

Dependent Claim
16 words
The annuloplasty ring of claim 6 wherein said attachment devices are manufactured from a Nickel-Titanium alloy.
Claim 11
Dependent Claim
118 words
A sizable self-molding annuloplasty ring for implantation in a heart valve annulus, comprising: a resilient inner sizing member in the shape of a continuous ring that has a relaxed diameter and can be stretched to a expanded diameter; and a plurality of support members each having a receiving lumen formed therein which is capable of receiving the inner sizing member, the inner sizing member being positioned within the lumens of the support members; wherein the plurality of support members are biased by the inner sizing member to engage one another and limit contraction of the inner sizing member to a contracted diameter; wherein the contracted diameter is larger than the relaxed diameter but smaller than the expanded diameter.
Claim 12
Dependent Claim
118 words
A sizable self-molding annuloplasty ring for implantation in a heart valve annulus, comprising: a resilient inner sizing member in the shape of a continuous ring that has a relaxed diameter and can be stretched to a expanded diameter; and a plurality of support members each having a receiving lumen formed therein which is capable of receiving the inner sizing member, the inner sizing member being positioned within the lumens of the support members; wherein the plurality of support members are biased by the inner sizing member to engage one another and limit contraction of the inner sizing member to a contracted diameter; wherein the contracted diameter is larger than the relaxed diameter but smaller than the expanded diameter.
Claim 13
Dependent Claim
31 words
The annuloplasty ring of claim 10 wherein said outer attachment sheath is selected from the group consisting of: biologically compatible fabric mesh; polyethylene terepthalate; polyester knit; PTFE knit; and ePTFE knit.
Claim 14
Dependent Claim
18 words
The annuloplasty ring of claim 10 wherein said outer attachment sheath comprises a medicament to induce tissue growth.
Claim 15
Dependent Claim
17 words
The annuloplasty ring of claim 10 wherein said resilient inner sizing member comprises a biologically compatible elastomer.
