Abstract

A system and method for performing an electrosurgical procedure are disclosed. The method includes obtaining information indicative of at least one physical characteristic of the patient and generating a reference voltage that is derived, at least in part, from the information. The reference voltage is coupled to a body of the electrosurgical apparatus, and the reference voltage is generated to a level so as to limit any difference between a voltage of the patient and a voltage of the body of the electrosurgical apparatus. In variations, the reference voltage is varied on an ongoing basis so as to adapt the reference voltage to one or more changing physical characteristics of the patient.
