Abstract
Abstract An artificial valve is provided which includes a holder for the sutures and needles. The holder positions the needles away from the valve but in a position where they may be readily reached during the valve replacement operation. The sutures are prethreaded through the valve sewing ring and are color coded for identification purposes when opposite ends are being tied together at the completion of the implantation procedure.
