Abstract
An electrosurgical system comprising, among other things, a control console to which detachably connects one or more electrosurgical probes capable of coagulating and ablating tissue. The control console generates a selectively variable power signal having a duty cycle that is dynamically modulated so as to maintain an average power level of a probe that is lower than a predefined maximum power level. The system can also incorporate both an impedance monitoring system and a current monitoring system as means to detect potentially dangerous situations, as well as a monitoring system for detecting impedance at relatively low power levels upon first activation of the probe. The probe can also incorporate non-volatile memory for storing probe-specific operating parameter data, probe usage data, data restricting probe use, error codes, and control console updates.
