Abstract
A surgical method aids identification of nerves in a body to help prevent damage to the nerves during surgery to the body proximate the nerves. An electrode introduced to within a body cavity through a catheter is placed proximate a nerve within the body cavity by a laparoscopic or robotic device. An exploratory probe placed in the body cavity is selectively placed along a presumed pathway of the nerve to provide an electrical signal through the nerve to the electrode. An analyzer interfaced with the electrode analyzes the electrical signal received at the electrode to determine the proximity of the exploratory probe to the nerve, allowing mapping of the nerve pathway through the body cavity.
