Abstract

An apparatus for protecting a nontarget body tissue of a patient during electrocautery surgery, an electrocautery probe being adapted to provide an electrical field to electrocauterize a target body tissue of the patient, includes a stent. The stent is adapted to detect the electrical field and to produce a field proximity signal in response to the detected electrical field. An electrical source provides electrical power to the probe. An electrical controller is adapted to receive the field proximity signal and to regulate electrical power to the probe in response to the field proximity signal. A method for protecting a nontarget body tissue of the patient during electrocautery surgery is also described.
