Abstract
Abstract This invention relates to a system used to fashion, size, and implant a tissue annuloplasty band. This system comprises (1) a device to cut tissue; (2) a device to fashion (i.e., roll, fold, bunch, etc.) the tissue into a band (i.e., the tissue annuloplasty band); and (3) a sizer that comprises an mounting ring which allows for determining and maintaining the proper size and shape of the tissue annuloplasty band while it is attached to the annulus of a heart valve. These components can be used alone, together as a system, or in any combination to fashion, size, and/or implant the tissue annuloplasty band.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
64 words
An annuloplasty band comprising an elongated substantially solid body of overlaid layers of graft tissue, said body being of a selected length and configured to be flexed into a generally curved configuration, and the band being configured to be sutured to a valvular annulus, said band being substantially solid throughout the length thereof, and said overlaid layers being formed by spirally wound graft tissue.
Claim 2
Dependent Claim
64 words
An annuloplasty band comprising an elongated substantially solid body of overlaid layers of graft tissue, said body being of a selected length and configured to be flexed into a generally curved configuration, and the band being configured to be sutured to a valvular annulus, said band being substantially solid throughout the length thereof, and said overlaid layers being formed by spirally wound graft tissue.
Claim 3
Dependent Claim
13 words
An annuloplasty band according to claim 1 wherein said graft tissue comprises pericardium.
Claim 4
Dependent Claim
14 words
An annuloplasty band according to claim 1 wherein said graft tissue comprises autologous tissue.
Claim 5
Dependent Claim
17 words
An annuloplasty band according to claim 1 further comprising a support structure attached to said graft tissue.
Claim 6
Dependent Claim
17 words
An annuloplasty band according to claim 4 wherein said support structure is internal to said graft tissue.
