We recently reported on an implantable nerve stimulator from Inspire Medical Systems that aims to help people with obstructive sleep apnea (OSA). The Apnex HGNS System is intended to work by restoring neuromuscular activity to the genioglossus muscle by stimulating the hypoglossal nerve synchronous with inspiration to mitigate upper airway collapse during sleep. Apnex Medical has received CE Mark approval for its Hypoglossal Nerve Stimulation (HGNS) system for the treatment of obstructive sleep apnea (OSA). A nerve cuff electrode on the distal end of the Stimulation Lead is implanted on a branch of the hypoglossal nerve (HGN) in the submandibular region.


This is similar to how the body’s natural neuromuscular physiology functions in people without OSA. The proximal end of the Stimulation Lead is tunneled under the skin to the Neurostimulator. Stimulation is generated by the Neurostimulator, synchronized with inspiration as measured by the Respiration Sensing Leads using bio-impedance, and delivered to the hypoglossal nerve by the Stimulation Lead. The hypoglossal nerve in turn controls muscles in the upper airway, ensuring they keep the airway open.


A clinical study is currently underway to test the effectiveness of the system in patients with OSA who were not helped with CPAP and other OSA treatments.
