New implant offers hope for sleep apnea patients who hate CPAP
NCT ID NCT06332404
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This registry follows 225 adults with moderate-to-severe obstructive sleep apnea who receive the Inspire hypoglossal nerve stimulation implant. The device is for people who cannot use CPAP, the standard treatment. Researchers will measure how well it reduces breathing pauses during sleep and how often patients actually use it in daily life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Inspire hypoglossal nerve stimulation device
- What this could lead to
- If successful, this registry could confirm that the Inspire device is a safe and effective long-term option for people with sleep apnea who cannot tolerate CPAP.
- What could go wrong
- This is an observational registry, not a controlled trial, so results may be less definitive. The device requires surgery and may not work for everyone.

Inclusion Criteria: Any patient implanted with or receiving the Inspire HNS system and who is able to give informed consent is eligible to participate in the registry. A patient is eligible for HNS implantation if he/she meets the following criteria: * At least 18 years old at the time of implantation * The patient suffers from moderate to severe OSA (15 events/h ≤ AHI ≤ 65 events/h) * The patient has failed, not tolerated or has a contraindication for continuous positive airway pressure (CPAP) and/or mandibular advancement device (MAD) therapy * Absence of complete concentric collapse of the level of the soft palate during Drug-Induced Sleep Endoscopy (DISE) Exclusion Criteria: * Body mass index (BMI) \>32 kg/m². * Combined mixed and central AHI is more than 25% of the total AHI * Patients with complete concentric collapse at the level of the soft palate or any other anatomical deviation that could impede the proper functioning of HNS * Patients with severely impaired neurological control over the upper airway * Pregnancy * Surgery performed on the soft palate in the past three months before implantation.
