  • Patent number: 11406813
    Abstract: Aspects of the disclosure include a bio-electric stimulation probe assembly including a patch including a first aperture and also a guide socket including a grommet and a second aperture. The guide socket is positioned on the patch such that the first and second apertures are aligned. The assembly further includes a guide including a tip that is positioned within and rotatable within the grommet. A probe of the assembly having at least one electrode is interconnected with the guide and extends through the first and second apertures. The guide and guide socket are collectively arranged and configured so that the guide has three degrees of rotational freedom with respect to the grommet thus meaning the probe correspondingly has three degrees of rotational freedom with respect to the grommet. Methods of using stimulation probe assemblies are also disclosed.

  • Patent number: 11406456
    Abstract: A navigation system or combination of navigation systems can be used to provide one or more navigation modalities to track a position and navigate a single instrument in a volume. For example, both an Electromagnetic (EM) and Electropotential (EP) navigation system can be used to navigate an instrument within the volume. The two navigation systems may be used separately to selectively individually navigate the single instrument in the volume. Disclosed are also systems and processes to determine a shape of the single instrument either alone or in combination with the position of the instrument. The instrument may be navigated with the addition of tracking devices or with native or inherent portions of the instrument.

  • Patent number: 11382550
    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.
