Abstract
Abstract A holder is provided for carrying a prosthetic ring which allows for manipulation and handling of the ring during implantation in a heart. The holder includes a holder body configured to fit the ring. A boss extends around the holder body. A backing lip extends from a proximal end of the boss and has a diameter that is greater than a diameter of the boss. A shoulder tab extends only partially around the distal end of the boss and extends beyond a diameter of the boss. The prosthetic ring mates with the boss and the backing lip to thereby hold the prosthetic ring.
