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: 20220362694Abstract: A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head.Type: ApplicationFiled: July 19, 2022Publication date: November 17, 2022Inventors: Brian Tucker, Bradley S. Honermann, Gary H. Gift, Brent A. Gulsvig, Kent Mehlhop, John R. Hacker, Mark S. Emery

Publication number: 20180257005Abstract: A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end and defines a central flow aperture. The baffle plate also defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate and spaced from and circumscribing the continuous groove. A filter assembly including the spin-on filter cartridge and a filter head is also disclosed wherein the filter cartridge is removably mountable on the filter head. When the spin-on filter cartridge is oriented on the filter head, a seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components.Type: ApplicationFiled: May 14, 2018Publication date: September 13, 2018Inventors: Philip E.
