Claim:
1. An electrosurgical system for treating tissue at a target site comprising: an electrosurgical probe comprising a shaft having a distal end and a proximal end, and an active electrode disposed near the distal end; a temperature sensor disposed near the electrosurgical probe distal end; a high frequency power supply coupled to the active electrode for delivery of a high frequency energy to said active electrode; and a controller in communication with the high frequency power supply, the controller operable to receive a temperature signal from the temperature sensor positioned in an electrically conductive fluid located at the target site, wherein the controller comprises a processor and a memory coupled to the processor, the memory comprising a program that when executed causes the processor to: command the high frequency power supply to deliver of the high frequency energy; command the high frequency power supply to automatically suspend delivery of the high frequency energy for a suspension period; monitor the temperature signal during the suspension period and determine a length of time of the suspension period, the suspension period defined as a length of time for a rate of change of the temperature signal to be less than a threshold value indicative of a stable temperature signal; and command the high frequency power supply to resume delivery of the high frequency energy at the end of the suspension period.
