energy is delivered to the jaws 26 28 when the jaws are in the position shown in fig6 to cauterize the tissue therebetween the procedure may be repeated for treatment of other tissue in the vicinity before the apparatus is withdrawn with the endoscope referring now to fig7 a 8 and 9 a second embodiment of the invention is disclosed which is substantially similar to the first embodiment but for the configuration of the clevis and the jaws i e the proximal actuation mechanism is as shown in fig1 in this embodiment the clevis means 124 includes an upper ring portion 132 for coupling to the distal end 2 of an endoscope the upper portion 132 may have an inner diameter which is substantially the same size as the outer diameter of the endoscope and cemented press fit or otherwise affixed to the distal end of the endoscope alternatively the upper ring portion may be sized to slide over the distal end of the endoscope the clevis means 124 also includes a lower side throughbore 133 which is dimensioned to allow the distal end of the coil to move therethrough jaws 126 128 are rotatably coupled to pivot pins 124 a 124 b of the clevis 124 the jaws are preferably substantially semi circular in shape as shown and are electrically isolated from each other by insulating washers 124 c 1 124 c 2 124 d 1 124 d 2 it should be mentioned that the clevis.
