Embodiment Construction

[0021] The present invention provides a non-invasive treatment for snoring and / or OSA that effectively creates a negative pressure within a person's mouth to relieve obstructed airways. Especially when a person, here a patient, is sleeping in a supine position, the soft tissues of the upper airway may fall against the floor of the pharynx, thereby blocking the air passage. In response, the device of the present invention is effective to create a negative pressure in the patient's mouth which pulls apart the soft tissue of the patient's upper airway to reopen the airway. The device is particularly advantageous in that when the patient's upper airway is open, the negative pressure generator will remove very little air from the oral cavity without creating a negative pressure in the oral cavity, thereby allowing the patient to breathe normally and comfortably. Breathe. Negative pressure is only created when the airway is blocked. Thus, the device does not touch the tongue, allo...

Abstract

Methods and devices are provided that are effective to remove an obstruction in a human airway related to snoring and / or OSA. In one embodiment, the device includes a mouthpiece that is adapted to form a sealed cavity within a human mouth, and a hollow elongate member having a first end that is coupled to the mouthpiece and that is in communication with the sealed cavity, and a second end that is adapted to be coupled to a negative pressure generator. In use, a negative pressure generator can be attached to the hollow elongate member to create a negative pressure in a human mouth in response to an obstructed airway, thereby removing the obstruction. In particular, this device is effective to pull a patient's tongue and / or soft tissues of the upper airway up and away from the posterior pharyngeal wall to reopen the airway.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Patent Application 10 / 769,180, filed January 30, 2004, entitled "Method and Apparatus for Alleviating Upper Airway Obstruction," the entire contents of which are incorporated by reference. technical field [0003] The present invention relates to methods and devices for reducing snoring and / or airway obstruction conditions, and more particularly to methods and devices for effectively creating negative pressure in a patient's mouth to remove upper airway obstruction and reduce or eliminate snoring and / or airway obstruction. Background technique [0004] More than 60 million Americans are affected by snoring and / or obstructive sleep apnea (OSA). Usually during waking hours, muscular tension in most individuals unconsciously holds the tongue, pharyngeal folds, soft palate, uvula, epiglottis, and pharyngeal floor in sufficient spatial relationship so as not to interfere with...
