Abstract: 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.

Abstract: Systems and methods for performing a multi-test-period titration for oral appliance therapy are described herein. A system includes a mandibular displacement device configured to be positioned in an oral cavity of a subject, a monitoring unit configured to sense one or more physiological inputs from the subject; and a control unit. The system is configured to configure at least one of the mandibular displacement device or the monitoring unit during the diagnostic sleep test protocol, perform the diagnostic sleep test protocol, configure at least one of the mandibular displacement device or the monitoring unit during the titration for oral appliance therapy protocol, and perform the titration for oral appliance therapy protocol.

Abstract: Systems and methods for setting one or more parameters for a multi-test-period titration for oral appliance therapy are described herein. A method can include performing a titration for oral appliance therapy during a first test period, identifying a variable associated with the titration performed during the first test period, and setting a parameter for a titration for oral appliance therapy to be performed during a second test period. The parameter can be dependent on the variable associated with the titration performed during the first test period. The method can also include performing the titration for oral appliance therapy during the second test period, and establishing an outcome of oral appliance therapy based on the titrations performed during the first and second test periods.

Abstract: An example method for detecting respiratory disturbances experienced by a subject can include receiving an airflow signal and at least one of an acoustic or vibration signal, where the airflow, acoustic, and/or vibration signals are associated with the subject's breathing. At least one feature can be extracted from the airflow signal and at least one feature can be extracted from at least one of the acoustic or vibration signal. Based on the extracted features, at least one respiratory disturbance can be detected. The respiratory disturbance can be flow limited breath or inspiratory flow limitation (“IFL”).

Abstract: Provided herein are systems, methods and devices for performing one or more titrations for oral appliance therapy. For example, a method for evaluating an outcome of oral appliance therapy in a subject is discussed herein. The method can include positioning an adjustable mandibular displacement device in an oral cavity of a subject and implementing an automatic titration protocol. The protocol can include controlling a protrusion level of the adjustable mandibular displacement device during a test period, monitoring physiological information from the subject during the test period, and analyzing the physiological information to evaluate the outcome of oral appliance therapy.

Abstract: Methods and apparatus for performing system validation and providing predictive criteria during remote titration of mandibular protrusion are disclosed herein. The effectiveness of oral appliance therapy can possibly be improved by screening obstructive sleep apnea subjects and prospectively identifying subjects suitable for oral appliance therapy. The methods and apparatus for performing system validation on an oral appliance therapy titration system are disclosed. In addition, methods and apparatus for providing predictive criteria during remote titration of mandibular protrusion are disclosed. Further, methods and apparatus for display results of remote titration of mandibular protrusion are disclosed.

Abstract: A system for reducing central sleep apnea (CSA) is described in which certain methods of increasing a patient's rebreathing during periods of the sleep cycle are used. By increasing rebreathing during periods of overbreathing, the over-oxygenation which typically results from the overbreathing period can be reduced, thus reducing the compensating underbreathing period and effectively reducing the loop gain associated with the central sleep apnea. Nasal occlusion and a leak resistant oral interface provide control for gas leaks from a patent interface.

Abstract: The present invention relates to systems and methods for automatically and continuously regulating the level of nasal pressure to an optimal value during OSA treatment. OSA therapy is implemented by a device which automatically re-evaluates an applied pressure and continually searches for a minimum pressure required to adequately distend a patient's pharyngeal airway. For example, this optimal level varies with body position and stage of sleep throughout the night. In addition, this level varies depending upon the patient's body weight and whether or not alcohol or sleeping medicine has been ingested.
