## 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

### Claim 1

A method of altering eating behavior of a subject comprising:
(a) providing a device body configured for partially blocking a pyloric aperture and sized for shuttling through a pylorus, said device body being attached to a tether having a length;
(b) selecting a tissue position in the stomach for anchoring an end of said tether, said tissue position being selected such that said length of said tether enables at least a portion of said device body to shuttle between a duodenum and said stomach;
(c) anchoring said end of said tether by penetrating tissue of said stomach at said tissue position.

### Claim 2 (depends on 1)

The method of claim 1, wherein said tether is axially elastic.

### Claim 3 (depends on 1)

The method of claim 1, wherein said penetrating is through a tissue fold of said stomach.

### Claim 4 (depends on 1)

The method of claim 1, wherein (c) is effected by delivering a t-bar anchor attached to said tether into or through said tissue.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 1)

The method of claim 1, wherein said shuttling is due to peristaltic forces in a gastrointestinal tract.

### Claim 7

A method of altering eating behavior of a subject comprising:
(a) providing a device body sized for shuttling through a pylorus, said device body being attachable to a tether having a length;
(b) selecting a tissue position in the stomach for anchoring an end of said tether, said tissue position being selected such that said length of said tether enables said device body to shuttle between a duodenum and said stomach when attached to said tether;
(c) anchoring said end of said tether by penetrating tissue of said stomach at said tissue position; and
(d) attaching said device body to said tether.

### Claim 8 (depends on 7)

The method of claim 7, wherein (c) and (d) are effected concomitantly.

### Claim 9

A method of altering eating behavior of a subject comprising:
(a) providing a device body configured for partially occluding a duodenum and being attached or attachable to a tether having a length;
(b) selecting a tissue position in the stomach for anchoring an end of said tether, said tissue position being selected such that said length of said tether enables at least a portion of said device body to reside within said duodenum;
(c) anchoring said end of said tether by penetrating tissue of said stomach at said tissue position.

### Claim 10 (depends on 9)

The method of claim 9, wherein said device body includes a plurality of discs.

### Claim 11 (depends on 10)

The method of claim 10, wherein at least one of said plurality of discs applies back pressure on the duodenal side of the pylorus.

### Claim 12 (depends on 9)

The method of claim 9 wherein said device body is concomitantly or subsequently attached to said tether after step (c).
