13. A tissue removal system comprising:
-
a generator configured to generate and deliver energy to a tissue removal device, the tissue removal device comprising; a tubular member having proximal and distal ends; a handle portion operatively extending from the proximal end of the tubular member; and a snare portion slidably supported within the tubular member and configured to extend from the distal end of the tubular member, the snare portion including first and second electrodes operably mounted thereto for receiving energy from the generator for treating tissue therebetween; a cutting member having a sharpened surface positioned between the first and second electrodes and configured to sever the treated tissue; and wherein at least one of the first and second electrodes includes at least one spacer mounted thereon for preventing contact between the first and second electrodes. - View Dependent Claims (14, 15)
