The implanted components of the hypoglossal nerve stimulating system include a neurostimulator that delivers safe levels of electrical stimulation to one hypoglossal nerve via a stimulation lead having a distal cuff electrode. Respiration sensing leads detect inspiration using bioimpedance, so that the system delivers stimulation synchronous with inspiration.
