Abstract
A system and method for detecting faults within an electrosurgical instrument having a shield and an active electrode uses multiple possible fault conditions. In one embodiment the monitoring system comprises an electrosurgical generator coupled to the electrosurgical instrument and adapted to deliver power to the active electrode of the electrosurgical instrument, monitoring circuitry coupled to the electrosurgical generator and the electrosurgical instrument.
