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.

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.

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.

Abstract: An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface, and a tube coating applied to the exterior surface via spraying of a homogeneous solution onto the endotracheal tube or immersion of the endotracheal tube in the homogeneous solution. A conductive electrode is formed on the tube coating. The conductive electrode is configured to receive the EMG signals from the laryngeal muscles.

Abstract: A drug delivery device for delivery of medicament having a delivery pump system and a cartridge system, the delivery pump system operating electromagnetically by driving two disk magnets that are housed within pump body inserts of the cartridge system. The displacement of the magnets and an elastomer membrane placed between the magnets of the cartridge system results in a volumetric change within two reservoirs and the flow of medicaments. The medicament flows from the reservoirs to the inlet/outlet members via the pump body inserts and discharged to a patient user's body through an infusion set.

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.

Abstract: A cartridge system of a multi-ported drug delivery device with independently actuated collapsible reservoirs, for delivery of medicaments, which includes membranes placed between disk magnets that are housed within pump body inserts. The pump body inserts having flow channels and fluid openings are between two inlet/outlet members with communication control through active valves and dynamically stressed membranes. The inlet/outlet members of the cartridge system each having a fluid outlet component and fluid openings are securely engaged to two or more reservoirs containing fluid medicaments. The cartridge system driven by the pump driver system delivers an appropriate dosage of medicament for treatment prescribed.
