Embodiment Construction

[0029] refer to figure 1 , describing the anatomy of the oral and nasal cavities and placement of the device of the present invention in relation to obstructive sleep apnea (OSA). The patient's upper teeth UT are anchored in the hard palate HP, while the lower teeth LT are anchored in the mandible or mandible LJ. The soft palate SP extends from the hard palate in a posterior or posterior direction as well as in an inferior direction, and together the hard palate and soft palate separate the nasal airway NA from the oral cavity OC. The lower extent of the oral cavity is primarily defined by the upper surface of the tongue T in this view, and it should be understood that both the soft palate SP and the tongue can be figure 1 The mobile structure moves between the positions shown in solid and dashed lines. The nasal airway NA extends down into the pharynx P, which generally defines the airway behind the soft palate SP and tongue T. The region on the tongue and soft palate sh...

Abstract

An oral device for improving airway patency comprises a base adapted to be held between a patient's upper and lower teeth and a tongue-engaging member. The tongue- engaging member engages the tongue and displaces the tongue anteriorly when the base is held between the patient's teeth. A vacuum is applied through the base and the tongue- engaging member in order to draw the soft palate against a posterior region of the tongue in order to stabilize the soft palate and open or clear the patient's airway.

Description

[0001] cross reference [0002] This application claims the benefit of US Application No. 12 / 840,076, filed July 2, 2010, which is incorporated herein by reference in its entirety. Background of the Invention [0003] 1. Field of Invention . The present invention generally relates to medical devices and methods. In particular, the present invention relates to an oral device that can be held in a patient's mouth for reducing the incidence of obstructive sleep apnea or snoring. [0004] Obstructive sleep apnea (OSA) is a serious medical condition caused by temporary blockage of the airways that occurs while a patient sleeps. Airway obstruction usually occurs between the soft palate and / or the back of the tongue and the pharynx. As the patient breathes, the reduced area in the upper airway can lead to snoring and, more seriously, OSA. [0005] Sleep disruption caused by OSA can lead to severe daytime sleepiness, chronic fatigue, headaches, depression, accidents, injuries, ...
