  • Patent number: 4878494
    Abstract: There is disclosed a method and apparatus for effecting cardio-valve replacement surgery. A clamp adapted to be fastened to an ether screen has multiple arms. These arms are linked together by a double clamp having two parts which are pivotable with respect to each other and within which the arms are both rotatable and slidable and which arms are simultaneously clamped in whatever position they may have been set. The clamping is effected by a draw bolt passing through both parts of the double clamp. At the free end of the arms is a clamp adapted to hold a replacement cardio-valve holder. The clamps and the arms are adjusted to present a replacement valve in a position such that it can be sutured into the heart of the patient without the surgeon having concern about the possibility of malalignment of the valve or suturing.
