A tongue grasping and restraining device holds the tongue securely during sleep in order to minimize the risk of the tongue slipping back and blocking the throat, a condition known as obstructive sleep apnea. Plural tongue gripping projections are coupled to upper and lower supports. The projections engage and hold the tongue. One or more of the upper and lower supports are biased together into a tongue engaging position. A tongue depressor can extend rearwardly and downwardly from the upper support to depress the user's tongue to further open the user's airway. The position of the tongue depressor can be adjustable. The upper support is coupled to the user's upper jaw, for example, to a denture, dental appliance or other form of an upper jaw coupler and can be pivoted thereto. The lower support can be hinged to, fixed to, or otherwise joined to a lower jaw coupler. A tube and rod mechanism in one embodiment couples the upper and lower jaw couplers together.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

A dental appliance is provided. The dental appliance includes a dental form configured to receive a portion of a dental arch of an individual, and an adhesive strip comprising a first side and a second side. The first side of the adhesive strip is attached to a portion of the dental form. The second side of the adhesive strip comprises a mucoadhesive configured to adhere the adhesive strip to a tongue of the individual such that the tongue of the individual can be selectively attached to the dental appliance.

Oral appliances, and systems and methods, which include oral appliances are described herein. An example oral appliance device for treatment of a sleep disorder or condition in a subject can include an upper portion configured to receive at least one maxillary tooth of the subject, and a lower portion configured to receive at least one mandibular tooth of the subject. The upper and lower portions are engageable such that the portions maintain a restricted orientation relative to each other when engaged, and the engaged restricted orientation is configured to maintain the mandible of the subject in a predetermined clinically beneficial orientation relative to the maxilla.

A nasal insert includes a housing having a circumferential wall defining an interior passage. The wall has a longitudinal gap extending along a length thereof, with an outer peripheral dimension of the housing being adjustable by varying the gap. A valve is in communication with the interior passage and limits a fluid flow through the interior passage in at least one direction. In another embodiment, a nasal insert includes a user interface having a tubular housing defining an interior cavity open at opposite ends. An exterior surface of the housing is adapted to interface with a nasal vestibule of a user. A base is received in the interior cavity of the housing and includes an exit port. A cap is connected to the base and has an input port. A valve member is disposed in an interior passage defined by at least one of the cap and base, with the valve member being moveably received in the interior passage. Methods of using and assembling the nasal inserts also are provided.

The present invention relates to a device to urge the mouth closed during sleep to reduce snoring and/or treat sleep disorders such as sleep apnea. In one aspect, the device includes a jaw-blocking object that is secured beneath the chin of a user and also contacting the clavicular region of the upper chest area. In another aspect, a device of the invention includes a jaw-blocking object in combination with a CPAP mask and headgear for use with a CPAP system.

A mandible displacement adjusting device includes an upper braces and a lower braces, wherein the upper braces and the lower braces have an upper teeth accommodation space and a lower teeth accommodation space, the upper teeth accommodation space and the lower teeth accommodation space are made based on the tooth shape, and fits on the upper and lower dental arches of the human body respectively, and the side walls of the upper braces and lower braces extend out a first positioning part and a second positioning part corresponding to the upper molar area and the lower molar area. When the user wear the upper braces and the lower braces, the first positioning part and the second positioning part would be driven to fit together, and maintain a movable displacement space, so that when the mandible of the human body is moved forward and fixed, it will not cause the mandible of the human body due to tightening, neither cause the discomfort at the condyle, while avoiding the back of the tongue slumping down and blocking the breathing passage.

A method includes receiving data associated with a sleep session of a user. The method also includes determining that the user is experiencing or has experienced an event based at least in part on the data. The method also includes causing pressurized air to be directed from a respiratory device to a multi-compartment bladder in response to determining that the user is experiencing or has experienced the event to aid in modifying a position of a head of the user.
