Abstract
Electrosurgical procedures. At least some of the example methods for detecting that an electrosurgical wand is effected by a blockage, including supplying a high frequency energy to an active electrode of an electrosurgical wand; drawing an electrically conductive fluid from the vicinity of the active electrode; sensing a temperature signal indicative of a temperature of the electrically conductive fluid drawn from the vicinity of the active electrode; and cycling the high frequency energy supplied upon the temperature of the electrically conductive fluid drawn from the vicinity of the active electrode exceeding a first threshold temperature.
