Patent number: 11918363Abstract: Stimulation and recording electrode assemblies that are particularly useful for Automatic Period Stimulation (APS). Such embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Certain embodiments include an electrode assembly having cuff including a body and two ears extending from the body. Within the body, at least one electrode is supported and connected to a lead wire assembly. The ears can be brought together to enlarge a gap in the body so that the electrode assembly can be fixated around a nerve. Other embodiments include an electrode assembly including first and second needle electrodes that each have a tip. A body is provided to interconnect the needle electrodes and can be manipulated to move the tips either toward or away from one another. Disclosed embodiments provide nerve monitoring and stimulation in cases where the nerve is only partially dissected.Type: GrantFiled: August 10, 2022Date of Patent: March 5, 2024Assignee: Medtronic Xomed, Inc.Inventors: Matthew L.
