The aura6000 is based on ImThera’s Targeted Hypoglossal Neurostimulation (THN) Sleep Therapy™ delivering neurostimulation to the tongue during sleep. The system is comprised of a surgically‐placed multi‐contact electrode specifically designed for the Hypoglossal nerve, and a lead that connects the electrode to a programmable implantable pulse generator (IPG) that is placed in the anterior chest wall. The device delivers muscle tone to key tongue muscles, preventing the tongue from collapsing into the upper airway, thus permitting normal breathing during sleep.
