Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject is at least 18 years of age;
• Subject has a diagnosis of severe OSA (65 ≤ AHI ≤ 100) based on a recent sleep study (within 12 months) OR Subject has a diagnosis of moderate to severe OSA (15≤AHI≤100) AND a baseline Body Mass Index of 32<BMI≤40 kg/m2;
• Subject has documented failure of, or intolerance to, positive airway pressure treatments (such as CPAP or BPAP machines; NOTE: PAP failure is defined as an inability to eliminate OSA (AHI > 15 despite PAP usage). PAP intolerance is defined as the inability to use PAP (> 5 nights per week, 4 hours of usage per night) or unwillingness to use PAP (e.g. patient returns the PAP system after attempting to use it).
• Subject is willing and able to have stimulation hardware permanently implanted and to use the patient remote to activate the stimulation;
• Subject is willing and able to return for follow-up visits, undergo sleep studies (including in-lab and at-home), and complete questionnaires related to the study;
• Subject is willing and able to provide informed consent.

You may not qualify if…

• Subject has a combination of central + mixed apneas > 25% of the total apnea-hypopnea index (AHI) based on a recent sleep study (within 12 months);
• Subject has any anatomical finding that would compromise the performance of upper airway stimulation, such as the presence of complete concentric collapse of the soft palate;
• Subject has any condition or procedure that has compromised neurological control of the upper airway;
• Subject is unable or does not have the necessary assistance to operate the patient remote;
• Subject is pregnant or plans to become pregnant;
• Subject has an implantable device that may be susceptible to unintended interaction with the Inspire System;
• Subject has a terminal illness with life expectancy < 12 months;
• Any other reason the investigator deems the subject is unfit for participation in the study.
