Abstract

A gastrointestinal bypass device for directing food and liquids from an esophagus and/or a proximal portion of a stomach into an intestines is described. The device comprises a receiver, a sleeve, and a device coupling. The receiver may be configured to be positioned in the esophagus and/or the stomach. A proximal portion of the receiver may be configured to open and close to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach. The receiver may be configured to receive food and liquids from the esophagus and/or a proximal portion of the stomach into a lumen of the receiver. The sleeve may be coupled to a distal portion of the receiver. The sleeve may be configured to be positioned in the stomach and the intestines. The sleeve may have a lumen in communication with the lumen of the receiver. The sleeve may be configured to direct the food and the liquids from the receiver into the intestines. The device coupling may be coupled to the distal portion of the receiver and/or a proximal portion of the sleeve. The device coupling may be configured to be coupled to one or more tissue anchors.

Claims

1. A gastrointestinal bypass device for directing food and liquids from an esophagus and/or a proximal portion of a stomach into an intestines, the device comprising:

a receiver configured to be positioned in the esophagus and/or the stomach, a proximal portion of the receiver configured to open and close to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach, the receiver configured to receive food and liquids from the esophagus and/or a proximal portion of the stomach into a lumen of the receiver; and

a sleeve coupled to a distal portion of the receiver, the sleeve configured to be positioned in the stomach and the intestines, the sleeve having a lumen in communication with the lumen of the receiver, the sleeve configured to direct the food and the liquids from the receiver into the intestines; and

a device coupling coupled by a standoff to the distal portion of the receiver and/or a proximal portion of the sleeve, the device coupling configured to be coupled to one or more tissue anchors.

2. The device of claim 1, wherein the receiver comprises a body and a plurality of fingers extending proximally from a proximal portion of the body.

3. The device of claim 2, wherein the fingers have an outward bias that is large enough to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach.

4. The device of claim 2, wherein the fingers have an outward bias that is small enough not to substantially interfere with the closing or normal functioning of the esophagus and/or a proximal portion of the stomach.

5. The device of claim 2, wherein the receiver further comprises one or more stiffening elements coupled to the fingers.

6. The device of claim 2, wherein the receiver further comprises webbing between the fingers.

7. The device of claim 2, wherein the receiver further comprises a receiver coupling coupled to a distal portion of the body.

8. The device of claim 7, wherein the receiver coupling includes one or more clips.

9. The device of claim 7, wherein the sleeve comprises a sleeve coupling configured to be coupled to the device coupling.

10. The device of claim 9, wherein the sleeve coupling includes a ring configured to be coupled to the clips.

11. The device of claim 2, wherein the receiver includes an extension coupled to a distal portion of the body.

12. The device of claim 1, wherein the device coupling includes a loop.

13. The device of claim 1, wherein the device coupling includes a halo.
