Unlike implanted hypoglossal nerve stimulators, the Zeus device doesn’t rely on strong muscle contractions that may disturb sleep. Instead, our TESLA method applies a gentle, external current to maintain the natural neuromuscular tone of the upper airway dilator muscles – the same tone that normally keeps the airway open while we are awake. Most patients don’t feel the stimulation, but it helps prevent the airway from collapsing once they fall asleep. This makes Zeus a comfortable, non-invasive alternative to surgery, while still addressing the root cause of snoring.
