The sensing lead incorporates a differential pressure sensor that detects respiratory cycles. The connector end of the lead is connected to the IPG. The sensor is implanted in between the intercostal muscle layers. The device senses relative pressure variations that correspond to the respiration cycle. The pressure waveform is monitored by the IPG and triggers stimulation therapy synchronous with inspiration
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.
