Technical approach

As reported
Mechanism

Hypoglossal nerve stimulation

Electrode stimulates the hypoglossal nerve, which controls tongue muscles. Rhythmic stimulation contracts the tongue forward, preventing airway collapse.

Simplicity

Single implant

Single device placed under the chin, reducing surgical complexity and complication risks versus multi-component systems.

Timing

Sleep-synchronous stimulation

Device detects sleep and adjusts stimulation based on breathing, delivering therapy only when needed.
