A stimulation system for delivery of a stimulation signal to a hypoglossal nerve of a patient to treat obstructive sleep apnea. The stimulation system includes an implantable receiver coil configured to be implanted under a mandible of the patient; a nerve electrode coupled to the implantable receiver coil, the nerve electrode configured to deliver the stimulation signal to the hypoglossal nerve of the patient; an external pulse generator configured to generate the stimulation signal; and an external transmitter coil configured to wirelessly transmit the stimulation signal from the external pulse generator to the implantable receiver coil, the external transmitter coil being carried by an adhesive patch configured to be placed on the skin adjacent the implantable receiver coil under the mandible of the patient.

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.

The present invention relates to an auricular neurostimulation device wearable by a user and configured to stimulate the Auricular Branch of Vagus Nerve (ABVN) on the user’s ear: the device comprises at least two electrodes designed to be located in the cymba and in the cavity of the cavum conchae respectively; the electrodes stimulate the nerve ramifications of the cymba and the cavum conchae, respectively, when an electrical voltage difference is applied between them. The invention further refers to an auricular neurostimulation system comprising an auricular neurostimulation device as described and a charging case where the device can charge an internal battery and where the device discharges into this case the data captured by the photoplethysmographic or biosensor during stimulation and sends them to a dedicated platform in the cloud. The invention also refers to a method of operation of an auricular neurostimulation system as described.

A stimulation device may include a tube, where the tube defines a lumen therein and a gas outlet. The gas outlet may be configured to allow gas to pass from the lumen to an exterior of the tube. The stimulation device may also include one or more first electrodes associated with the tube, one or more second electrodes, and a nasal cavity interface proximal of the gas outlet and the one or more first electrodes.

Provided is an electrical stimulation therapy apparatus for dysphagia including an input unit configured to receive user information including a food type divided into a low-viscosity liquid and a high-viscosity liquid, a stimulation unit including a plurality of channels and configured to stimulate swallowing muscles of a user, and a processor configured to generate a control command for driving the stimulation unit, wherein the processor sequentially stimulates the swallowing muscles including a bilateral suprahyoid muscle (SH), a thyrohyoid muscle (TH), and a sternothyroid muscle (StH) of the user according to a preset muscle activation sequence based on the user information.

The present disclosure relates to a method for increasing an amount of air and/or oxygen passing through an airway of an individual, reducing airway restrictions in an individual, increasing airway patency and/or maintaining airway patency in an individual, decreasing snoring, obstructive sleep apnea, or a combination thereof, in an individual. The method may comprise stimulating at least four regions of the individual's neck, where two of the at least four regions of the individual's neck are anterior triangle regions on opposing sides of the individual's midline, and another two of the at least four regions of the individual's neck are anterior triangle regions on opposing sides of the individual's midline, posterior to the two of the at least four regions. The present disclosure also discusses related devices and systems.

Intraoral appliances are disclosed that provide electrical stimulation to tissue in a patient's oral cavity in a manner that reduces apnea events during sleep. A representative appliance can induce a current or currents through tissue and/or anatomical structures in a manner that maintains upper airway tone and/or patency.

A respiration promoting apparatus and a method for promoting respiration for coordinately stimulating a phrenic nerve of a patient for activating a diaphragm of the patient by a pulsating field that is produced by interference stimulation principles.

An example method includes receiving one or more physiological signals; detecting an apnea event based on the one or more physiological signals; determining that the apnea event cannot be characterized as one of a normal, OSA (obstructive sleep apnea), CSA (central sleep apnea), or combination OSA/CSA event; and outputting an electrical stimulation as a default based on determining that the apnea event cannot be characterized as a normal event, an OSA event, a CSA event, or combination OSA/CSA events.

Control systems and methods for delivery of energy that may include control algorithms that prevent energy delivery if a fault is detected and may provide energy delivery to produce a substantially constant temperature at a delivery site. In some embodiments, the control systems and methods may be used to control the delivery of energy, such as radiofrequency energy, to body tissue, such as lung tissue.
