IMPLANTABLE DEVICE FOR DIRECTIONAL CONTROL OF FLOW WITHIN THE ANATOMIC TRACTS OF THE BODY
First Claim
1. An implantable device for the directional control of flow through an anatomic tract of a body, the device comprising:
- a biocompatible valve with a substantially cylindrical housing sized to fit the anatomic tract, the valve further comprising;
a first set of projections disposed circumferentially around an interior wall of the housing, wherein a distal end of each of the projections in the first set of projections projects a first distance towards the center of the housing at a first angle relative to the wall of the housing.

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.

17. A method for fabricating an implantable device for the directional control of flow through an anatomic tract of a body, the method comprising:
-
forming a mold for a valve, wherein the valve is sized to fit the anatomic tract and comprises a first set of projections disposed circumferentially around an interior wall of a housing, wherein a distal end of each of the projections in the first set of projections projects a first distance towards the center of the housing at a first angle relative to the wall of the housing; injecting a biocompatible material into the mold; and releasing a formed valve from the mold. - View Dependent Claims (18, 19, 20)
