The Oventus O2Vent is a custom-made comfortable oral device that is designed for snorers and people with obstructive sleep apnea. It received FDA clearance in April 2016.
The device directs the flow of air through to the back of the throat and bypasses nasal and soft palate obstructions and prevents tongue obstruction. The unique design makes it especially suitable for patients who experience nasal congestion and who may find CPAP and other oral appliances difficult to use, the manufacturer states.
A recent Oventus clinical trial demonstrated significantly reduced AHI and snoring was reduced or eliminated in 100% of patients studied.
