The MATRx plus is indicated for use by a lay person in a home and hospital use under the direction of a Health Care Professional (HCP). MATRx plus records the following data: patient respiratory nasal airflow, snoring, blood oxygen saturation, pulse, respiratory effort and body position during sleep. MATRx plus uses these recordings to produce a report for the HCP that may aid in the diagnosis and assessment of sleep disordered breathing for adult patients. The MATRx plus device may also be used with an automated mandibular positioner that uses feedback control to record changes in the patient's respiratory status related to repositioning of the mandible during an overnight study. MATRx plus uses these recordings to produce a report for the HCP that can be used to prospectively identify patients with mild to moderate obstructive sleep apnea who may be suitable for oral appliance therapy and to recommend a target mandibular position. The use of the device does not replace the need for follow-up testing to determine the initial and ongoing effectiveness of the therapy as recommended by clinical practice guidelines.

MATRx plus is a ventilatory effort recorder and closed loop auto-titration device for oral appliances. MATRx plus is a 5-channel battery-powered respiratory pressure sensor and oximetry system. MATRx plus provides recordings of respiratory pressure, snoring, respiratory effort, pulse rate, oxygen saturation, and body position during sleep. The device is worn on the patient's abdomen attached to a reusable effort belt and all relevant respiratory information during sleep is collected via nasal cannula, pulse oximetry module, and respiratory effort sensor. The disposable plastic nasal cannula is connected to the MATRx plus recorder and fixed at the patient's nose. The cannula is dual lumen and functions to individually sample the pressure from each naris. The oximetry sensor is fixed at the patient's finger and connects directly to the device. The Recorder receives input from the sensors and wirelessly transmits the data to a bedside Tablet during the study. The Tablet is set up through a connection to the web portal by the healthcare professional (HCP) prior to deploying the device to the patient for home use. The Tablet runs the MATRx plus application and records and stores the data. The MATRx plus application on the Tablet is also used to guide the user through the set up and conduct of the study through a stepwise user interface. At the end of a recording, the Tablet advises the patient if sufficient data for analysis were recorded during the night. During an auto-titration study, the patient wears temporary Titration Trays connected to a mandibular positioner. During the study, the device moves the mandible in response to respiratory events in order to determine if the patient is a suitable candidate for oral appliance therapy. After recording, the MATRx plus must be returned to the HCP. The data are automatically uploaded to the secure Portal where they can be accessed and downloaded to the Data Viewer. The Data Viewer can generate a report with the recorded and analyzed data (respiratory pressure, respiratory effort, pulse rate, oxygen saturation) to aid in diagnosis (when used as a ventilatory effort recorder) or to assist the HCP in the clinical management of oral appliance therapy for patients with obstructive sleep apnea. The device is intended to be used on adult patients, upon referral from their healthcare provider. The device is not to be used as an apnea monitor or in a life supporting or life sustaining situation and must not be used in the vicinity of an MRI device.

This De Novo request is for an expanded indication (new intended use) for use with an automated mandibular positioner that uses feedback control to record changes in the patient's respiratory status related to repositioning of the mandible during an overnight study. The device is an automated temporary oral appliance that manipulates the mandible through multiple protrusion levels during an overnight sleep study in the home. The device uses the same interface as the MATRx plus Home Sleep Apnea Test, also from Zephyr Sleep Technologies, cleared under product code MNR, regulation 21 CFR 868.2375, cleared in K163665. These components include the recorder, tablet, oximeter, effector belt, and nasal cannula. The MATRx plus device for a titration study includes a mandibular positioner to determine an optimal titration position based on inputs of airflow and an oxygen desaturation index (ODI) of less than 10 events per hour. The device analyses the collected information and generates a report to assist the Healthcare Provider in the clinical management of oral appliance therapy for patients with mild to moderate obstructive sleep apnea. From this report, patients may be informed on the future efficaciousness of oral appliance (OA) therapy. Specifically, the clinical management may be assisted by this type of oral appliance assessment study by prospectively identifying patients that are expected to achieve therapeutic success with oral appliance therapy. The oral appliance assessment study also includes the provision of a recommended target protrusive setting for the mandible through use of a legally marketed intraoral appliance (regulated under 21 CFR 872.5570, product code LQZ). The target protrusive setting is the amount of mandibular protrusion where the patient is expected to achieve efficacious therapy with the intraoral appliance and is used by the HCP to more effectively complete the titration process. The use of the MATRx plus device for an oral appliance assessment study does not replace the clinical titration process or the need for follow-up testing to determine the initial and ongoing therapy as recommended by clinical practice guidelines. The MATRx plus test identifies patients as suitable for intraoral therapy if a mandible protrusion level can be found where the patient has an oxygen desaturation index (ODI) of less than 10 events per hour with a 4% desaturation criterion.

Overnight use of a temporary oral appliance to determine in which patients with obstructive sleep apnea mandibular advancement by an oral appliance will reduce obstruction of airflow and thereby to identify patients suitable for oral appliance therapy. The device is also used to recommend a target mandibular position that will reduce obstruction of airflow in patients determined to be suitable for oral appliance therapy.

The RCMP appliance is a device used in the clinical setting to identify patients with obstructive sleep apnea that will be successfully treated with an oral appliance. A temporary appliance fits to the patient's teeth and incrementally and reversibly advances the patient's mandible anteriorly with respect to the maxilla while the patient is under full polysomnographic monitoring. The repositioning of the mandible pulls the tongue forward and increases the patient's airway space. Such obstruction can be a causative factor in obstructive sleep apnea and snoring. The RCMP is used in the clinical setting by a technician to advance the mandible until the polysomnographic data indicates removal of the obstruction of airflow in the airway. The device is used to recommend a target mandibular position that will reduce obstruction of airflow in patients determined to be suitable for oral appliance therapy. The RCMP appliance consists of upper and lower disposable dental titration trays that are used to hold onto the teeth by means of a quick-set retention material. The trays attach to a mandibular positioner that retracts and extends a rod to adjust the tray positioning by means of a small force linear actuator. By extending the linear actuator rod attached to the upper tray, the RCMP pushes on the upper teeth and pulls on the lower teeth, thus displacing the jaw. RCMP software interacts with the polysomnography to allow the technician to control fine adjustments of the relative position of the mandible.
