Inspire Upper Airway Stimulation therapy is an FDA-approved treatment for some people with moderate to severe OSA who are unable to tolerate or get relief from continuous positive airway pressure (CPAP). In contrast to CPAP, Inspire therapy is implanted inside the body and works with a patient's natural breathing process. Controlled by the patient sleep remote, the system includes a breathing sensor and a stimulation lead powered by a small battery. During sleep, the system senses breathing patterns and delivers mild stimulation to the tongue and other soft tissues of the throat to keep the airway open.
