Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The LinguaFlex™ Tongue Retractor (LTR) is an investigational medical device that is inserted into the tongue to lessen its backward movement during sleep. This helps to keep the airway open during sleep so that the tongue doesn't block the airway causing obstructive apnea or narrow it enough to cause snoring. This study will monitor the effectiveness of the LTR device in the reduction of Obstructive Sleep Apnea and snoring over the course of a one-year treatment period.
