Is this trial a fit for you?

Likely a good fit

Adults implanted with or scheduled to receive an Inspire upper airway stimulation device who can give informed consent and will attend routine clinic follow-up are ideal candidates.

Probably not a fit

People without an Inspire implant, those unlikely to survive a year, or patients unable to attend routine follow-up visits are unlikely to receive benefit from participating.

What this trial studies

EURO-STIM is a longitudinal observational registry collecting real-world outcomes and device adherence data from patients treated with the Inspire upper airway stimulation system. Participants receive routine clinical care with no required study-specific interventions or extra testing, and data are captured during standard follow-up visits. The registry aims to document the life cycle of Inspire use, including therapy adherence, clinical outcomes, and device-related events across multiple European centers. Eligibility is limited to patients implanted with or receiving an Inspire device who can give informed consent and attend routine clinic visits.

Why it matters

Potential benefit: If successful, the registry could improve understanding of long-term adherence and outcomes with Inspire, helping clinicians optimize patient selection and management.

How similar studies have gone: Prior controlled trials and registries of hypoglossal nerve stimulation, including earlier Inspire studies, have shown reductions in OSA severity and improved adherence, so this registry extends existing real-world evidence.
