Abstract

A system and method for performing an electrosurgical procedure are disclosed. The method includes applying an active electrode to a patient and placing a return electrode on the patient so as to create a current path in tissue of the patient between the active electrode and the return electrode. A conductive element, which is operatively coupled to the active electrode, is coupled to a reference voltage with a low impedance path and a voltage is imparted to the active electrode so as to generate current in the current path. Any undesirable current flow that would otherwise flow from the active electrode to the reference voltage through the patient is limited to reduce a risk of harm to the patient.
