Patent ID: 7799021

Claim:
An electrosurgical apparatus comprising: at least one energy source operable to at least partly concurrently provide a first signal and a second signal, said first and second signals having different frequencies, said at least one energy source being operable to deliver said first signal to a first electrically conductive component for treating a region of tissue within a patient's body, said region of tissue comprising a neural structure, said at least one energy source being operable to deliver said second signal to a second electrically conductive component for stimulating the production of a third signal by a nerve within said patient's body for transmission along a neural pathway of said patient's body, said third signal being transmitted along said neural pathway at least partly concurrently with the provision of said first signal to said patient's body; and at least one signal processor operable to receive said third signal, to process said third signal, and to produce an output based on a processing of said third signal, said output being indicative of an effect of said first signal on said neural pathway along which said third signal is being transmitted.
