Abstract
An implantable system for the treatment of obstructive sleep apnea by electrical stimulation of the musculature of the upper airway. The system employs one or more sensors to determine the onset of an apnea event. Upon sensing of the onset of an apnea event, the stimulation generator provides a signal for stimulating the muscles of the upper airway at a varying intensity wherein the intensity is gradually increased during the course of the stimulation. The signal is coupled to the muscles to be stimulated by an electrode connected to the stimulation generator by an insulated lead.
