Abstract
An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. The ultrasonic waveguide of the apparatus is preferably provided with an improved support member at the distal-most node thereof, which support member desirably functions to resist bending moments created in the waveguide, attendant to operation of the clamping mechanism, while sealing the region adjacent to the waveguide.
