Abstract: A surgical system 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.

Abstract: The invention provides a monitoring tag for wearing about the appendage of an individual. It includes a self-contained transmitter module that is located in a housing and transmits radio signals to a base unit, for receipt by the base unit if within a predetermined range. If the individual wearing the monitoring tag moves outside this range then the base unit can trigger an alarm or send a warning signal. The housing has an opening for receiving the end of a flexible elongate strap to secure the tag around the appendage of the individual. The strap is attached to the housing inside the opening using a clip, which has structure for fixedly securing it to the strap and structure for fixedly securing it in the opening. Once the clip is attached to the housing it cannot be removed unless a weakened or frangible region between the securing structures is broken.
