Implantable device for directional control of flow within the anatomic tracts of the body
First Claim
1. An implantable device for a 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 flaps comprising a plurality of microstructures formed on a surface of the first set of flaps and configured to impede a first flow of fluid in a first direction, the first set of flaps disposed circumferentially around an interior wall of the housing, wherein a distal end of each of the flaps in the first set of flaps project a first distance towards a center of the housing at a first angle relative to the interior wall of the housing; and
a second set of flaps disposed circumferentially around the interior wall of the housing, wherein a distal end of each of the flaps in the second set of flaps project a second distance towards the center of the housing at a second angle relative to the interior 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.
