What this Trial Is About

The goal of this interventional study is to assess the safety and performance of the XII Medical Hypoglossal Nerve Stimulation (HGNS) System in people who have moderate to severe Obstructive Sleep Apnea (OSA). Participation in this study involves being implanted with a Neurostimulator which provides electrical stimulation of the hypoglossal nerve (HGN). Participants will receive treatment at home during sleep, and participate in sleep studies to track and record the quality of the sleep. Participants will be monitored over the course of the study.
