1. An ultrasonic clamp coagulator apparatus comprising:

  • an ultrasonic waveguide having a proximal end and a distal end;

    an ultrasonically actuated curved end-effector attached to the distal end of the waveguide;

    a tissue pad having a first tissue engaging surface and a second engaging surface having a protrusion; and

    a curved clamp member pivotable with respect to the end-effector and having an open position in which at least a portion of the clamp member is spaced from the end effector and a closed position in which the clamp member is adjacent to the end effector and that the motion from the closed position to the open position occurs in a plane substantially perpendicular to the plane of curvature of the end effector for clamping tissue between the clamp arm and the end-effector, the clamp member comprising a slot for slidably receiving the protrusion.
