## Abstract

Gastric space occupying devices are provided that include a stent configured for deployment in the gastrointestinal tract of a patient, and in particular, for deployment in the esophagus or the stomach. Secured to the stent is an expandable member that is adapted to reside within the patient's stomach. When expanded, the expandable member occupies a predefined volume within the patient's stomach and is further tethered to the deployed stent, thereby retaining or anchoring the expandable member within the stomach. Methods and systems for the deploying the space occupying devices are also provided.

## Claims

### Claim 1

A method of anchoring a space occupying device within a patient's stomach, comprising:
implanting a stent in the esophagus or stomach of the patient;
deploying an expandable member in the patient's stomach spaced apart from the stent, the expandable member having a wall defining a sealed volume; and
attaching the expandable member to the stent.

### Claim 2 (depends on 1)

The method of claim 1 wherein the stent is implanted in the patient's esophagus.

### Claim 3 (depends on 1)

The method of claim 1 wherein the stent is implanted in the patient's stomach.

### Claim 4 (depends on 1)

The method of claim 1 wherein the expandable member is secured to the stent prior to implanting the stent.

### Claim 5 (depends on 1)

The method of claim 1 wherein the expandable member is secured to the stent prior to implanting the expandable member.

### Claim 6 (depends on 1)

The method of claim 1 wherein the stent is a self-expanding stent.

### Claim 7 (depends on 1)

The method of claim 1 wherein the expandable member is inflatable.

### Claim 8 (depends on 7)

The method of claim 7 further comprising inflating the expandable member after deployment.
