The Inspire® Respiratory Sensing Lead (Model 4340) is designed to detect respiratory effort. The lead features a pressure sensitive membrane that converts the mechanical energy of respiration into an electrical signal. The lead incorporates a standard connector for coupling to the Inspire implantable pulse generator (IPG) for treatment of obstructive sleep apnea.
An assembly of implantable devices intended for home management of obstructive sleep apnoea (OSA) by improving airway patency through stimulation of the hypoglossal nerve [targeted hypoglossal nerve stimulation (THN)], synchronous with respiration during sleep, to elicit a neuromuscular response at the base of the tongue. It consists primarily of three connected implanted components: a respiratory movement sensor, a pulse generator, and a lead to provide respiration-dependent (and alternatively, fixed-rate) electrical stimulation to the hypoglossal nerve; a patient-operated remote controller/charger and software for device configuration by a healthcare professional are typically included.
