Abstract
An electrosurgical medical device includes an elongate shaft defining a proximal end, a distal end, and a lumen there through. A fluid conduit is disposed within the lumen. A first electrode is at least partially disposed within the lumen and extends distally from the distal end of the shaft, the first electrode is sized and configured to cut tissue with radiofrequency energy. A second electrode is arranged in a bipolar configuration with the first electrode, the second electrode is coupled to ground and configured to receive radiofrequency energy from the first electrode. The second electrode is defined by at least a portion the shaft and extending a distance away from the distal end of the shaft.
