Primary Outcome Measures:
  • Mean change in AHI measured through in-lab polysomnography (PSG) compared to baseline. [ Time Frame: 3 and 12 months post-implant ] [ Designated as safety issue: No ]
  • Adverse events and Serious Adverse events peri and post-operatively [ Time Frame: 3 and 12 months post-operative ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Mean change in Quality of Life outcomes measured with ESS (Epworth Sleepiness Scale) as compared to baseline. [ Time Frame: 3 and 12 months post-operative ] [ Designated as safety issue: No ]
  • Mean change in Quality of Life outcomes measured with FSS (Fatigue Severity Scale) as compared to baseline. [ Time Frame: 3 and 12 months post-implantation ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: THN Therapy Device: aura6000 System
The aura6000 device is an implanted hypoglossal nerve stimulator designed to maintain wakeful muscle tone of the tongue during sleep. It is implanted through a short surgical procedure. The implant is programmed to provide the optimal stimulation parameters for the patient. The therapy is controlled by a hand-held remote control allowing the patient to start, stop, and pause the therapy during times of sleep.
