1. A method for performing an annuloplasty on a heart valve, the method comprising the steps of:
- providing an elongated length of autologous or non-autologous graft tissue;
fashioning the elongated length of graft tissue into an elongate band comprising a plurality of overlaid layers of the graft tissue;
wherein the fashioning comprises rolling the elongated length of graft tissue along an axis thereof so as to create the band comprising the plurality of overlaid layers of graft tissue;
sizing the elongate band to the annulus of the valve; and
implanting the elongate band of graft tissue onto the annulus of the valve;
wherein the elongated length of graft tissue is rolled about a flexible axle having two opposing ends, and further wherein the step of implanting the elongate band of graft tissue comprises the following sub-steps;
(a) positioning the band around the annular peripheral surface of a mounting ring,(b) attaching the opposing ends to one another so as to secure the band to the mounting ring,(c) using the mounting ring to position the elongate band of graft tissue proximate the annulus of the valve,(d) securing the elongate band of graft tissue onto the annulus of the valve, and(e) separating the mounting ring from the elongate band of graft tissue.

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.

6. A method for performing an annuloplasty on a heart valve, the method comprising the steps of:
-
fashioning an elongated length of autologous or non-autologous graft tissue into an elongate substantially solid band comprising a plurality of overlaid layers of the graft tissue; sizing the elongate substantially solid band of autologous or non-autologous graft tissue to the annulus of the valve; and implanting the sized elongate substantially solid band of autologous or non-autologous graft tissue onto the annulus of the valve wherein the band of tissue is sized by positioning thereof on an adjustable mounting ring and adjusting the size of the adjustable mounting ring, and further wherein the mounting ring is used to guide the band of tissue into place for implantation. - View Dependent Claims (7, 8, 9, 10, 11)
