First Claim
Patent Images
1. An apparatus for use with a clamp including first and second clamp members, the apparatus comprising:
- an electrosurgical power supply and control apparatus;
a tissue stimulation apparatus configured to provide pulses of tissue stimulation energy varying in amplitude over a range of 1 mA to 20 mA;
a base member including a mating structure and defining a groove therein, the mating structure being configured for removably securing the base member to the first clamp member;
a support member, the groove formed within the base member being configured to receive the support member;
a coagulation electrode carried by the support member, the coagulation electrode coupled with the electrosurgical power supply and control apparatus; and
a stimulation electrode carried by the support member, the stimulation electrode coupled with the tissue stimulation apparatus,wherein a distal end of the stimulation element is disposed distal to a distal end of the coagulation element.
