The Inspire device is an implanted hypoglossal nerve stimulator for obstructive sleep apnea. Inspire sleep apnea device represents a major alternative for CPAP-intolerant patients meeting specific criteria. This guide covers how it works, eligibility, and effectiveness.
How Inspire works
Implanted device with three components:
- Generator (placed under chest skin)
- Sensor lead (detects breathing)
- Stimulation lead (around hypoglossal nerve)
During sleep, the device stimulates the tongue muscle in synchronization with breathing, keeping the airway open. Activated nightly via remote.

- Age 18+ (recently expanded to 13+ in some patients)
- CPAP intolerance documented
- Specific anatomic features (drug-induced sleep endoscopy may be required)
- No complete concentric collapse at velum
The procedure
- Outpatient surgery (about 2 hours)
- Three small incisions
- Activation 1 month after surgery
- Adjustment over weeks to months
Effectiveness
Clinical trials showed:
- ~70% reduction in apnea-hypopnea index
- Substantial improvement in daytime sleepiness
- Quality of life improvements
- Long-term durability
Cost
Total cost typically $30,000-50,000:

- Surgical procedure with risks
- Not all patients respond
- Battery replacement every ~10 years
- MRI compatibility considerations
