Claim 0:
1. A tissue removal system, comprising:
an electrosurgical generator including an active electrode port and a return electrode port;
an active electrode device configured to connect to the active electrode port; and
a tubular return tissue guard configured to connect to the return electrode port, the tubular return tissue guard having a proximal end defining a proximal opening, a distal end defining a distal opening, and an intermediate waist portion between the proximal end and the distal end, wherein a diameter of the intermediate waist portion is less than a diameter of the proximal opening and a diameter of the distal opening, and wherein an inwardly-facing surface of the tubular return tissue guard defines a tubular channel and includes a first electrically-conductive portion and a second electrically-conductive portion, the first and second electrically-conductive portions disposed on the inwardly-facing surface of the tubular return tissue guard and extending from the intermediate waist portion to the distal end of the tubular return tissue guard, the first electrically-conductive portion configured to connect to the return electrode port and the second electrically-conductive portion electrically isolated from the first electrically-conductive portion and configured to connect to the return electrode port.
