Abstract
The systems and methods described herein related generally to a device that enables the directional control of flow through an anatomical tract of the body. More particularly, the device described herein includes a valve from a plurality of projections. In some implementations, the projections are configured as flaps, posts, or any combination thereof. In some implementations, the device is implanted into a patient's esophagus to prevent gastroesophageal reflux disease. The plurality of projections allow flow into a patient's stomach while substantially preventing a backflow of undesired fluids from the patient's stomach to the patient's esophagus.
