Vessel sealing wave jaw
First Claim
1. In a forceps having first and second jaw members operatively attached adjacent a distal end thereof and a handle assembly adjacent a proximal end thereof, the jaw members being movable between an open position and a closed position about a pivot assembly, the improvement comprising opposing inner facing surfaces disposed distal to the pivot assembly each having a plurality of different waveforms disposed thereon, the inner facing surface of at least one of the jaw members having at least one fenestration disposed therethrough between the plurality of waveforms.

Abstract
A forceps for clamping, grasping, manipulating, coagulating/desiccating and cutting tissue includes a shaft portion having a proximal end, a distal end and first and second jaw members pivotally attached to the distal end of the shaft by a pivot assembly. Each of the jaw members including an opposing inner facing surface having a plurality of wave forms disposed thereon for engaging tissue therebetween. The wave forms disposed on the inner facing surface of the second jaw member being complimentary to the wave forms on the inner facing surface of first jaw member. A handle portion having an actuating assembly is attached to the proximal end of the shaft for imparting movement of the first and second jaw members from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second clamping position wherein the jaw members cooperate to grasp tissue therebetween. One embodiment of the forceps includes a pair of electrodes clamped on the inner facing surface of each jaw member for imparting electrosurgical energy to the tissue grasped therebetween.
