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.

Abstract: A nerve integrity monitoring device includes a control module and a physical layer module. The control module is configured to generate a payload request.
