  • Patent number: 11980752
    Abstract: A surgical tool including first connecting elements, contacting elements, and conductive elements. The contacting elements are configured to contact nerve tissue of a patient. The conductive elements extend from the connecting elements to the contacting elements. The conductive elements have respective insulative outer layers. The insulative outer layers isolate the conductive elements from each other. The first connecting elements are configured to connect to and receive monophasic stimulation pulses from second connecting elements on a modular stimulation module. The modular stimulation module is configured to connect to the tool and other tools via the second connecting elements. The conductive elements are configured to transfer the monophasic stimulation pulses from the connecting elements to the contacting elements.

  • Patent number: 11918363
    Abstract: 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.

  • Publication number: 20230301596
    Abstract: 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.

  • Patent number: 11412986
    Abstract: 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.
