NCT03210142

Brief Summary

The purpose of this study is to assess the effect of Transvenous Hypoglossal Nerve Stimulation (tHGNS) on tongue position in the upper airway. Activation of the HGN will cause contraction of the genioglossus muscle, which will move the tongue forward, opening the upper-airway and reducing apnea-hypopnea events in patients with Obstructive Sleep Apnea (OSA). A transvenous approach will be less risky and traumatic than current HGNS systems that require an open surgical approach to wrap a cuff electrode around the HGN.
