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.

Claim 19
Dependent Claim
50 words
18 . A method for performing an annuloplasty on a heart valve comprising the steps of: fashioning an elongated length of graft tissue; sizing the elongated length of graft tissue to the annulus of the valve; and implanting the elongated length of graft tissue onto the annulus of the valve.
Claim 20
Dependent Claim
50 words
18 . A method for performing an annuloplasty on a heart valve comprising the steps of: fashioning an elongated length of graft tissue; sizing the elongated length of graft tissue to the annulus of the valve; and implanting the elongated length of graft tissue onto the annulus of the valve.
