Publication number: 20240100341Abstract: Neuromodulation of cranial nerves can be used to treat sleep or breathing disorders, among other diseases and disorders. A neuromodulation system can include a housing configured for implantation in an anterior Cervical region of a patient, such as at or under a mandible of the patient, such as at least partially in one or mote of a submental triangle, a submandibular triangle, and a carotid triangle. The system can include an electrode lead coupled to the housing, and the electrode lead can include an electrode configured to be disposed at or near a cranial nerve target in the patient. The system can be configured to generate electrical neuromodulation signals for delivery to the cranial nerve target using the electrode.Type: ApplicationFiled: October 4, 2023Publication date: March 28, 2024Inventors: Lynn Elliott, Stephen C.

Patent number: 11395921Abstract: A neuromodulation catheter is positionable in a blood vessel having a wall for use in delivering therapeutic energy to targets external to the blood vessel. An electrically insulative substrate such as an elongate finger is carried at a distal end of the catheter body. The substrate has a first face carrying a plurality of electrodes, and a second face on an opposite side of the substrate from the first face. The finger is biased such that when expanded within the blood vessel, it forms a spiral configuration with the first face facing outwardly to bias the electrodes in contact with the blood vessel wall.Type: GrantFiled: August 8, 2019Date of Patent: July 26, 2022Assignee: NuXcel2 LLCInventors: Stephen C.

Patent number: 10857352Abstract: A neuromodulation system includes a first therapy element adapted for positioning within a superior vena cava, and a second therapy element adapted for positioning within a pulmonary artery. The first therapy element is carried on a first elongate flexible shaft, and the second therapy element is carried on a second elongate flexible shaft. One of the first and second shafts is slidably received within a lumen of the other of the first and second shafts—so that the second therapy element may be advanced within the body relative to the first therapy element. A stimulator is configured to energize the first therapy element within the first blood vessel to deliver therapy to a first nerve fiber disposed external to the superior vena cava and to energize the second therapy element within the pulmonary artery to deliver sympathetic therapy to a second nerve fiber disposed external to the pulmonary artery.Type: GrantFiled: December 27, 2017Date of Patent: December 8, 2020Assignee: NUXCEL LimitedInventors: Terrance J Ransbury, Richard S Stack, William E Sanders, Stephen C Masson
