摘要：
Methods and devices for providing a gas pathway between the nasopharynx and the Eustachian tube are provided. One device may include a lumen with a valve. A portion of the valve may be tethered to adjacent muscle. Another portion of the valve may be tethered to adjacent cartilage. When the muscle contracts the valve may open through movement of the tethers, and provide a gas pathway between the nasopharynx and the Eustachian tube.
