Annuloplasty ring delivery system and method

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.
