Abstract
Methods and devices are provided that are effective to remove an obstruction in a human airway and/or maintain an open airway. The methods and devices are particularly useful for patients suffering from snoring and/or OSA, and/or preventing upper airway obstructions in patients undergoing anesthesia. In one embodiment, the device includes a mouthpiece that is adapted to form a substantially 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 substantially 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 counteract the collapse of a patient's soft tissues of the upper airway to reopen the airway. The mouthpiece can also be used in combination with a nasal mask. In another embodiment, the oral appliance above also comprises a nasal mask, wherein the nasal mask provides a means of ventilation support, including but not limited to total mechanical ventilation, positive-end expiratory pressure, or continuous positive airway pressure. In use, such a device can provide complete patient ventilation and maintain an open upper airway.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
