Patent number: 11793250Abstract: Implementations described herein include surgical helmet assemblies that have a helmet enclosure shaped to encircle a head of a user. The helmet enclosure retains a fan and includes a brow bar portion at a front of the helmet enclosure that is shaped to extend along a brow or a forehead of the user and having a light positioned therein. The helmet enclosure also includes a stabilizer extending downward from the helmet enclosure in front of the ears of a user, a face shield that is transparent and coupleable to at least the brow bar portion, a headband shaped to extend across an occiput region of the user's head, and a surgical garment for covering at least the head and shoulders of a user in use. The brow bar portion includes vents disposed therein to direct airflow pushed through the helmet enclosure from the fan onto the user.Type: GrantFiled: September 30, 2021Date of Patent: October 24, 2023Assignee: Zimmer, Inc.Inventors: Ganesh B Pavalarajan, Douglas C Barker, John Bartholomew, George Brand, Anna Diorio-Blum, Larry Keith Hooks, Jr., Steven E.

Publication number: 20230020138Abstract: The present disclosure relates to neuromuscular stimulation and sensing cuffs. The neuromuscular stimulation cuff has at least two fingers and a plurality of electrodes disposed on each finger. More generally, the neuromuscular stimulation cuff includes an outer, reusable component and an inner, disposable component. One or more electrodes are housed within the reusable component. The neuromuscular stimulation cuff may be produced by providing an insulating substrate layer, forming a conductive circuit on the substrate layer to form a conductive circuit layer, adhering a cover layer onto the conductive circuit layer to form a flexible circuit, and cutting at least one flexible finger from the flexible circuit. The neuromuscular stimulation cuff employs a flexible multi-electrode design which allows for reanimation of complex muscle movements in a patient, including individual finger movement.Type: ApplicationFiled: September 15, 2022Publication date: January 19, 2023Inventors: Chad E.
