  • Patent number: 5716401
    Abstract: A holder for a prosthetic heart valve is disclosed. The holder, comprising a holder assembly disposed at the distal end of an elongate handle, includes a plurality of distally-projecting fingers adapted to engage the commissure posts of a stented prosthetic valve. The commissure-engaging fingers are movable in a radially-inward direction toward the longitudinal axis of the holder. A mechanism is provided for retaining the fingers in an inwardly-moved position. When the commissure posts of the valve are coupled to the fingers, inward movement of the fingers causes the commissure posts to be deflected inward with respect to the valve, improving the implanting surgeon's access to the valve's suture ring and surrounding tissue.
    Type: Grant
    Filed: December 1, 1995
