Patent number: 11944371Abstract: A bipolar electrosurgical device including an outer shaft, an inner shaft, first and second electrode surfaces, and an irrigation channel. The outer shaft defines a lumen, a proximal end and a distal end forming a cutting window. The inner shaft is rotatably disposed within the outer shaft, and defines a distal portion forming a cutting tip. The cutting tip and the cutting window combine to define a cutting implement. The first and second electrode surfaces are electrically isolated, and are formed at the cutting implement. The irrigation channel extends parallel to the outer shaft, and terminates in at least one outlet port. The outlet port is proximally spaced from the cutting window and is located radially outside of the outer shaft. Fluid (e.g., saline) is emitted at the exterior surface of the device near the cutting window and is readily present for interacting with the electrode surfaces.Type: GrantFiled: December 17, 2021Date of Patent: April 2, 2024Assignee: Medtronic Xomed, Inc.Inventors: John R Prisco, Eric P.

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. Cantwell, David C. Hacker, John R. Prisco

Publication number: 20230301596Abstract: Aspects of the disclosure relate to pledget stimulation/recording electrode assemblies that are particularly useful for automatic periodic stimulation. Embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Disclosed embodiments include an electrode assembly having one or more electrodes rotatably supported by and positioned within a pledget substrate. The flexible pledget substrate conforms and fixates to bioelectric tissue to secure the electrode assembly in position, wrapped around the target tissue. In some embodiments, the pledget substrate includes two bodies, each including at least one electrode, the two bodies being selectively separable so that the bodies can be repositioned with respect to one another. The electrode assembly further includes a lead wire assembly including at least one insulating jacket positioned around a wire core.Type: ApplicationFiled: May 24, 2023Publication date: September 28, 2023Inventors: Matthew L.

Patent number: 11412986Abstract: Aspects of the disclosure relate to methods of conducting an intraoperative procedure including providing an electrode assembly having a pledget substrate having a surface that is hydrophilic, at least one electrode supported by and positioned within the pledget substrate, and a lead wire assembly interconnected to the at least one electrode. Methods can further include creating an incision to access bioelectric tissue of a patient and applying the pledget substrate to the tissue, such as a nerve, for example. The pledget substrate conforms and fixates to the tissue to secure the electrode assembly in position. The electrode is then activated to record bioelectric responses of or stimulate the tissue. In some embodiments, the pledget substrate includes two bodies, each including at least one electrode, the two bodies being selectively separable so that the bodies can be repositioned with respect to one another.Type: GrantFiled: October 5, 2018Date of Patent: August 16, 2022Assignee: Medtronic Xomed, Inc.Inventors: Matthew L.
