System and method for treating obstructive sleep apnea
One aspect of the present disclosure relates to a system for treating obstructive sleep apnea in a subject. The system can include a power source and a neuromuscular stimulator in electrical communications with the power source. The neuromuscular stimulator can include a controller and at least one electrode. The controller can be configured to receive certain power and stimulation parameters associated with a therapy signal from the power source. The at least one electrode can be configured to deliver the therapy signal to a target tissue associated with control of a posterior base of the tongue of the subject.
1. A system for treating obstructive sleep apnea (OSA) in a subject, the system comprising:
a power source;
an electromyogram (EMG) sensor configured to detect muscle activity of a muscle that controls tongue movement;
a neuromuscular stimulator in electrical communication with the power source, the neuromuscular stimulator comprising an array of electrodes configured to stimulate distal arborizing branches of a hypoglossal nerve of the subject;
a controller programmed to deliver a therapy signal to the array of electrodes, in response to decreased muscle activity detected from the EMG sensor, to stimulate the distal arborizing branches of the hypoglossal nerve to open an oropharyngeal airway to an laryngeal introitus.
2. The system of claim 1 , wherein the neurostimulator comprises a lead and the array of electrodes and the EMG sensor are disposed on the lead.
3. The system of claim 1 , wherein the neuromuscular stimulator further includes a housing, the controller contained within the housing, an electrical lead connected to the housing, and the array of electrodes connected to the electrical lead.
4. The system of claim 1 , wherein power source is external to the neuromuscular stimulator.
5. The system of claim 1 , wherein the controller is programmed with pre-determined, set programs; and adaptive, dynamic programs.
