ABSTRACT:
A surgical implement particularly useful for implanting a prosthetic valve in an excised annulus includes a manually grippable handle, and a suture retainer carried by the handle and having an outer face carrying a coiled spring whose coils define an annular array of slits each having opposed yielding surfaces for receiving and releasably retaining sutures between selected coils. Optimum spacing of the sutures according to the shape of the excised annulus is attained by providing reference ribs between selected coils of the spring, and also by making the outer annular face of the suture retainer of substantially the same shape as that of the excised annulus. Implements are described, with a suture retainer and without a suture retainer, including an illuminating device for artificially illuminating the working area. Also described is a method of implanting a prosthetic valve in a quick and efficient manner using such implements.
