An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is assembled directly into a hermetic feedthrough of the implantable device and utilizes the feedthrough housing as a sustaining structure for connector clamping. The receptacle contacts detachably connect proximal lead contacts to corresponding feedthrough pins, which provide pass-through connections to electronic circuitry contained in a hermetically sealed case. The receptacle contact has resilient contact tines designed to engage a corresponding lead contact in a sliding manner. The receptacle contact is integrated with a contact guard which protects the receptacle contact from inadvertent handling damage. The contact guard is substantially more rigid than the resilient contact to resist deformation. The contact guard protectively shields the receptacle contact tines and prevents unintended contact tine excursion. In one embodiment, the contact guard is pre-attached to the receptacle contact prior to joining to the feedthrough pin. In another embodiment, the contact guard is an integral part of the feedthrough pin. Numerous embodiments with contact preload are provided.

A pivoting utility receptacle assembly for use with a work surface, such as a desktop. The assembly includes a base member positionable within an opening in the work surface and a receptacle member that is pivotally mounted to the base member. A biasing member is engaged between the receptacle member and the base member, and biases the receptacle member to a partially exposed position with respect to the base member. The assembly also has a locking mechanism including a latch on the receptacle member which engages the base member and secures the receptacle member in a closed position with respect to the base member until such time as it is desired to expose the receptacle member. The movement of the receptacle member out of the base member under the influence of the biasing member is controlled by a movement controlling assembly engaged between the receptacle member and the base member.

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.
