The Model 2200P-47E Posterior Lead is provided sterile for implantation. It is a flexible lead that contains bipolar platinum/iridium tip and ring electrodes with an insulated lead body. Electrical current is delivered to the tip electrode which is implanted to be in contact with the posterior trunk of the vagus nerve to block nerve signals. The ring electrode is placed in contact with the stomach to measure lead impedance. Sutures are used to anchor and stabilize the lead placement. The lead is connected to the implanted Rechargeable Neuroregulator. The Posterior Lead contains a white stripe along the lead body, a white suture tab, and a white coating on its' conductor cables to distinguish it from the Anterior Lead.
An implantable wire, insulated with non-conductive material except at its electrode(s), intended to be used to make an electrical connection between a pulse generator and the vagus nerve for vagus nerve stimulation (VNS).
