A Study to Determine the Flow Changes And/or AHI Reduction When Stimulating Two Targets (neural And/or Muscular) for the Treatment of Obstructive Sleep Apnea in Adult Subjects

Exclusion Criteria

• •Patients meeting any of the following criteria will be excluded from participation in this study:
• •Major anatomical or functional abnormalities that would impair the ability of the electrode arrays to be positioned.
• •Significant comorbidities that contraindicate surgery or general anesthesia.
• •Significant tongue weakness.
• •Aerodigestive tract tumor or reconstructive surgery performed at the same time as neck dissection.
• •Any other chronic medical illness or condition that contraindicates a surgical procedure or general anesthesia in the judgment of the investigator.
• •Prior surgery or treatments that could compromise the placement and effectiveness of the electrode array systems:
• •* Airway cancer surgery or radiation, or
• •* Mandible or maxilla surgery in the previous 3 years (not counting dental treatments).
• •Other upper airway surgery to remove obstructions related to OSA in the previous 3 months (e.g., uvulopalatopharyngoplasty (UPPP), tonsillectomy, nasal airway surgery).
• •Prior hypoglossal nerve stimulation device implantation.
• •Currently pregnant or breastfeeding during the study period.
• •Concomitant oral or pharyngeal surgery.
