Nyxoah is a medical device company focused on the development and commercialization of hypoglossal nerve stimulation therapy for the treatment of obstructive sleep apnea (OSA).The company has developed a battery-free, leadless, minimally invasive neurostimulator capable of delivering bilateral hypoglossal nerve stimulation for patients with moderate to severe OSA who have failed at conventional positive airway pressure therapy.Nyxoahs therapy consists of a tiny neurostimulator that is implanted in the chin area in a minimally invasive surgery.

The system, which is powered by a miniature external battery, is placed under the chin and stimulates the tongue nerve.In March 2019, Nyxoah received CE marking for its novel hypoglossal nerve stimulation therapy for treatment of obstructive sleep apnea.

In January 2021, Nyxoah received CE mark magnetic resonance imaging (MRI) conditional labeling for the current Genio neurostimulation-based OSA therapy for treatment of obstructive sleep apnea.
