Primary Outcome Measures:
  • Reduction in Apnea-Hypopnea Index (AHI) [ Time Frame: 3, 6, and 12 months post implant ]
    Change from baseline in AHI measured through in-lab polysomnography (PSG).

  • Reduction in Oxygen Desaturation Index (ODI) [ Time Frame: 3, 6, and 12 months post implant ]
    Change from baseline in ODI measured through in-lab polysomnography (PSG).

  • Freedom from Serious Adverse Events (SAE) [ Time Frame: 1 and 12 months post implant ]
    Adverse events and Serious Adverse events post-operatively

Secondary Outcome Measures:
  • Improvement in sleep fragmentation [ Time Frame: 3, 6, and 12 months post-implant ]
    Mean change in microarousal index as compared to baseline.

  • Improvement in SAQLI [ Time Frame: 3, 6, and 12 months post implant ]
    Mean change in SAQLI (Sleep Apnea Quality of Life Index) as compared to baseline.

  • Improvement in ESS [ Time Frame: 3, 6, and 12 months post implant ]
    Mean change in ESS (Epworth Sleepiness Scale) as compared to baseline.

Arms Assigned Interventions
Experimental: aura6000 THN Therapy
The aura6000 THN system will be implanted and activated for nightly therapy during sleep.
Device: aura6000 THN 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.
