Abstract
An assembly for holding a substantially flexible suture guide of predetermined length in a substantially taut position used to achieve a suture line having a dimension equal to the length of the suture guide, such as the circumference about a heart valve annulus. The assembly includes a rigid suture guide holder having a surface against which the length of suture guide is releasably positioned. The guide holder can have a shape or geometry, such as a circumference or circumferential segment, equivalent to the shape or geometry of the intended suture line. The shape of the guide holder can therefore be selected to hold the suture guide in the shape most advantageous to placing the desired suture line. The assembly further includes a mechanism for releasably binding the suture guide to the surface of the holder and a detachable handle extendibly attached to the holder by means of a lanyard so that the handle can be detached to afford an unobstructed view of the surgical site, but cannot be removed from the surgical site until the holder has also been removed.

31. An annuloplasty prosthesis delivery system, comprising:
-
an annuloplasty prosthesis;
a rigid body defining a surface against which the annuloplasty prosthesis is fitted and held in a shape substantially equivalent to at least a portion of the valve annulus, and an outer periphery of the annuloplasty prosthesis extends outward from the rigid body;
at least one suture secured to the rigid body and passing through the annuloplasty prosthesis tautly attaching the annuloplasty prosthesis about the surface;
a handle assembly including a distal housing, the distal housing releasably secured to the rigid body. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. An annuloplasty prosthesis delivery system, comprising:
-
an annuloplasty prosthesis;
a rigid body defining an outer edge about which the annuloplasty prosthesis may be fitted;
at least one suture tautly attaching the annuloplasty prosthesis about the edge and having a portion exposed on the rigid body which can be cut to release the annuloplasty prosthesis from the rigid body; and
a handle secured to the rigid body that may be removed during a surgical implant procedure to allow for easier visibility of the annuloplasty prosthesis. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)

55. A method of delivering and implanting an annuloplasty prosthesis at an annulus implant site, comprising:
-
providing an assembly of an annuloplasty prosthesis and a rigid body, the rigid body defining a surface about which the annuloplasty prosthesis may be fitted such that an outer periphery of the annuloplasty prosthesis extends outward from the rigid body, the annuloplasty prosthesis being tautly attached about the surface with at least one suture attached to the rigid body and passing through the annuloplasty prosthesis, the suture having a portion exposed on the rigid body;
coupling a handle assembly to the rigid body;
delivering the annuloplasty prosthesis/rigid body assembly to the annulus implant site using the handle assembly;
decoupling the handle assembly from the prosthesis/rigid body assembly and removing the handle assembly from the annulus implant site;
securing the annuloplasty prosthesis to the annulus while the annuloplasty prosthesis remains attached about the surface; and
severing the suture at the portion exposed on the rigid body and removing the rigid body and severed suture from the secured annuloplasty prosthesis. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62)
