Summary
The purpose of this clinical trial is to demonstrate long-term safety and efficacy of the Inspire system. The Inspire Upper Airway Stimulation (UAS) therapy is intended to treat moderate-to-severe obstructive sleep apnea by improving airway patency through stimulation of the hypoglossal nerve. Study objectives include demonstrating that the Inspire system improves key indices of sleep apnea in a pre-specified percentage of patients.
