ABSTRACT:
A controlled return path monitoring system is used in combination with an electrosurgical generator unit employing an active electrode for performing electrosurgery. The system includes internal electrode which is disposed, in use, within the body of a patient in proximity to the active electrode and is electrically connected to the electrosurgical generator unit so as to provide a preferred current return path back to the electrosurgical generator unit, and an external electrode which is disposed, in use, on the body of the patient and is electrically connected to the electrosurgical generator unit so as to provide a safety current return path back to the electrosurgical generator unit. A detector monitors the return current flow from the two electrodes back to the electrosurgical generator unit and controls the unit in accordance with the monitored return current flow, e.g., shuts off the unit when the flow exceeds a predetermined level.
