Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This post-approval study is a condition of FDA approval and will collect long-term safety and effectiveness data on an expanded population that includes patients with very severe obstructive sleep apnea (65\<AHI≤100 events/hr), as well as those with a higher BMI (32\<BMI≤40 kg/m2). Participants will be implanted with a commercially available Inspire UAS System. In addition, participants will receive a patient remote which is used to initiate therapy each night.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Subject is at least 18 years of age;
2. 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;
3. 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).
4. Subject is willing and able to have stimulation hardware permanently implanted and to use the patient remote to activate the stimulation;
5. 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;
6. Subject is willing and able to provide informed consent.

Exclusion Criteria

1. 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);
2. 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;
3. Subject has any condition or procedure that has compromised neurological control of the upper airway;
4. Subject is unable or does not have the necessary assistance to operate the patient remote;
5. Subject is pregnant or plans to become pregnant;
6. Subject has an implantable device that may be susceptible to unintended interaction with the Inspire System;
7. Subject has a terminal illness with life expectancy \< 12 months;
8. Any other reason the investigator deems the subject is unfit for participation in the study.
