1. A method of limiting a temperature of a fluid aspiration element associated with an electrosurgical wand comprising:
supplying a high frequency energy to an active electrode of an electrosurgical wand;
drawing an electrically conductive fluid through the fluid aspiration element and away from the active electrode;
sensing a temperature signal indicative of a temperature of the fluid aspiration element; and
cycling the high frequency energy supplied, upon the temperature exceeding a first threshold temperature, the first threshold temperature indicative of an inadequate fluid flow condition through the fluid aspiration element that may cause high temperatures of the fluid aspiration element and wherein cycling the high frequency energy is configured to regulate the temperature of the fluid aspiration element.
