Automated, snore activated electro-mechanical mandibular advancement device
First Claim
1. A mandibular advancement device for abating sleep disorders, comprising:
- a maxillary jaw tray configured to fit over a plurality of upper teeth of a patient;
a mandibular jaw tray configured to fit over a plurality of lower teeth of a patient;
an electro-mechanical actuator connecting said maxillary and mandibular jaw trays; and
comprising a cart that moves linearly in response to the expansion or contraction of a nitinol wire assembly, and a protruding arm configured to ratchet a ratchet gear with each actuation; and
a microcontroller in communication with at least one sensor, said microcontroller configured to, in response to an occurrence of a predetermined event, send a signal to an actuator indicating that the mandibular jaw tray should extend.

Abstract
An automated mandibular advancement device (MAD) is described for the treatment of sleep disorders involving the occlusion of upper airway gas flow during sleep; one example being obstructive sleep apnea. In embodiments, a MAD projects the lower jaw forward only after the patient has fallen asleep. Embodiments of the may track patient sleep parameters for later review by the patient and/or the treating physician to assess the quality of sleep and efficacy of the treatment regime. An actuator placed laterally within a band allows the integral microprocessor to actuate the lower jaw tray forward upon sensing of snoring activity (or upon exceeding a pre-set timer threshold).
