Tongue-first
The tongue is a primary contributor to upper-airway collapse. REVIDAM addresses it directly instead of repositioning the jaw.
Obstructive sleep apnea · Oral device
Keeping the airway open, starting with the tongue.
REVIDAM is developing a Glossal Advancement Device: a lower-dental appliance with a flexible, porous mesh that gently stabilizes the tongue forward and upward to help maintain upper-airway patency during sleep.
01 The problem
A common condition, poorly served.
In obstructive sleep apnea the upper airway repeatedly collapses during sleep, which is linked to hypertension, heart disease, stroke and diabetes. Today's options leave many patients untreated.
80%+
of obstructive sleep apnea cases are estimated to be undiagnosed
Published estimates 40–45%
of patients reported as non-adherent to CPAP therapy
Clinical literature $2.5B
US sleep apnea device market in 2024, projected ~$4.6B by 2034
Statista 02 Our approach
Support the tongue. Leave the jaw alone.
During sleep the tongue can fall back and block the airway. The device is designed to hold it forward while still allowing natural movement such as swallowing, without moving the jaw.
Illustrative renders of the proposed mechanism. Not clinical data.
Gentle, distributed support
A soft, flexible interface is designed to spread contact across the tongue rather than concentrate it at a single point.
Fitted to the patient
A personalized lower-dental platform is intended to give the interface a stable, comfortable foundation through the night.
