*Federal Register* notice: FDA is classifying neuromuscular tongue muscle stimulators and their use for reducing snoring and obstructive sleep apnea into Class 2 (special controls). The action is based on a 2020 de novo classification request from Signifier Medical Technologies for its eXciteOSA device. As part of the classification, FDA identified the device as a removable intraoral mouthpiece that uses electrodes to deliver neuromuscular stimulation to the tongue to strengthen tongue musculature to reduce snoring and obstructive sleep apnea.
