METHODS AND SYSTEMS FOR IMPROVING AIRWAY PATENCY
First Claim
1. A method for stabilizing a soft palate in a patient'"'"'s oral cavity, said method comprising:
- selecting a patient diagnosed with sleep apnea;
engaging a member across an engagement region of the patient'"'"'s tongue, wherein a region of tongue anterior to the member is unconstrained so that it can rise in a superior direction relative to the engagement region; and
applying a vacuum to a space between the tongue and the palate to cause the anterior tongue region to rise in the superior direction.

Abstract
An oral device for improving airway patency comprises a tongue constraint and a negative pressure source. The tongue constraint engages the patient'"'"'s tongue to maintain a clear region below the palate in an oral cavity and allow an anterior portion of the tongue to rise. By applying a negative pressure in the clear region, an airway behind the soft palate or tongue of the patient can be maintained. The tongue constraint is usually connected to an anchor. The anchor may be held between the patient'"'"'s teeth or may engage the inferior surface of the palate. Another oral device for improving airway patency comprises a lateral tongue structure and a negative pressure source.

15. An oral device for temporary placement in a patient'"'"'s oral cavity, said device comprising:
-
a base adapted to be held between the patient'"'"'s upper and lower teeth; a tongue-engaging member coupled to the base and having a posterior structure that engages an engagement region of the tongue and an anterior structure that allows a tongue region anterior to the member to rise relative to the engagement region when the base is held between the teeth; and a vacuum conduit coupled to the base and/or the tongue-engaging member and configured to apply a vacuum to a region of the oral cavity between the patient'"'"'s tongue and palate. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
