(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.
