Neurostimulation

Implantable Device

Hypoglossal Nerve Stimulation is indicated for Obstructive Sleep Apnea only. It is based on controlling tongue position and movement during sleep by electrical stimulation of the hypoglossal nerve, which innervates the tongue. A battery powered pulse generator is inserted under the skin of the chest. Electrodes are tunneled from the generator to the neck area, and attached to the hypoglossal nerve. It is turned ON at night when one is to sleep only. As one inhales and the chest expands, a sensing mechanism provides feedback to the generator, which then sends signals to an activating electrode to the hypoglossal nerve pushing the tongue forward opening the upper airway.

Phrenic Nerve Stimulation is indicated for Central Sleep Apnea only. It is based on controlling diaphragm contraction to simulate inhalation by stimulating the phrenic nerve, which innervates the diaphragm. A battery powered pulse generator is inserted under the skin of the chest and electrodes are attached to the phrenic nerves. A sensing electrode detects when one is asleep and in a horizontal position, and the pulse generator is activated sending signals to the diaphragm to contract, leading to inhalation.

Non-Implantable Device

Tongue stimulating device is indicated for obstructive sleep apnea. It is based on stimulation of the tongue at fixed periods and frequency during the day to maintain tonal endurance during sleep, preventing collapse and closure of the airway. The stimulator is a portable device.
