Abstract

A device for modifying an eating behavior of a subject is provided. The device includes a device body which is attachable to GI tract tissue of a subject and functions in altering an eating behavior thereof.

Claims

1. A device for modifying an eating behavior of a subject comprising:

(a) a device body being sized and configured for passing through a pyloric opening,

(b) a tether having a first end attached to said device body and a second end anchorable through a stomach tissue fold, said second end including a washer for preventing said second end from burying into said stomach tissue under a pulling force on said tether.

2. The device of claim 1, wherein at least a portion of the device body is hollow.

3. The device of claim 1 wherein said device body has a volume of 4 cm3 or less.

4. The device of claim 1 wherein said device body has a surface area 15 cm2 or less.

5. The device of claim 1, wherein at least a portion of said tether can reversibly increase in length by least 25%.

6. The device of claim 1, wherein at least a portion of said device body is capable of moving between a stomach and a duodenum when attached to said tissue of said stomach.

7. The device of claim 1, wherein said device body has a maximum diameter of 2 cm.

8. The device of claim 1, wherein said tether is 0.5-10 cm in length.

9. The device of claim 1, wherein said device body includes one or more discs.

10. The device of claim 1, wherein the device is configured for at least partially blocking said pylorus from the stomach or duodenal side.

11. The device of claim 1, wherein said device body is capable of moving between an antrum and a duodenum with natural peristaltic and reflux forces.

12. The device of claim 1, wherein said device body consists of one or more polymers.

13. The device of claim 1, wherein said device body is non-expandable.

14. A method of anchoring a device in the stomach of a subject comprising passing a first end of a tether through a stomach tissue fold and through a washer wherein a second end of said tether is attached to a device body.

15. A method of anchoring a device in the stomach of a subject comprising passing a tether through a stomach tissue fold and through a washer wherein said tether is attached to a device body.

16. A method of anchoring a device in the stomach of a subject comprising passing a tether through a stomach tissue fold and through a washer attached to a device body, thereby attaching said tether to said tissue and said device body.

17. A method of anchoring a device in the stomach of a subject comprising passing a tether through a stomach tissue fold and attaching a first end of said tether to a device body whereas second end of said tether includes a washer.
