Patient is between 21 and ≤70 years of age
Subject has moderate to severe obstructive sleep apnea (defined as apnea-hypopnea index of 15-50 events/hour on baseline/screening polysomnogram)
Subject is intolerant of positive airway pressure therapy (defined as \<2 hours of sleep time with use per night for at least 5 nights per week as measured objectively by evaluation of continuous positive airway pressure (CPAP) machine memory chip and interpreted by the study sleep medicine specialist)
Subject signs and dates a written informed consent form and indicates understanding of the study procedures and risks

Usually NOT eligible if any of the following apply:

Exclusion Criteria:
Any evidence that apnea is not caused by base of tongue (i.e., central apnea, neurologic disorder, retropalatal collapse, nasal obstruction)
Any condition likely requiring MRI or has a metal implant
Any factor that, in the surgeon's judgment, would pose a risk to surgery or placement of a long-term implanted device
Any factor that, in the surgeon's judgment, would make the subject unlikely to respond to Magnap treatment
Congenital anomalies of the larynx, pharynx, or trachea or any other anatomical abnormality of the head, neck, or chest that would be a contraindication to placement of the Magnap device and usage of the external device
