Abstract
Systems and methods for improving airway patency are disclosed. An oral device is positioned in the oral cavity and applies a negative pressure to the oral cavity. The oral device has pressure delivery ports directed toward an anterior surface of the soft palate when positioned therein. The negative pressure generates an air flow out of the oral cavity. A pressure tube is coupled to the oral device to provide the applied negative pressure. A pressure source is coupled to the pressure tube to generate the applied negative pressure. A collector is coupled to the pressure tube and/or pressure source to collect liquid, typically saliva, from the air flow out of the oral cavity. The collector is disposed outside of the oral cavity and coupled to the oral device.
