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

1. A space occupying device for occupying a volume within a patient'"'"'s stomach, comprising:

an expandable stent configured to be implanted in the patient'"'"'s esophagus or stomach;

an expandable member having a wall defining a sealed volume therein when expanded, the expandable member also having a tethering region;

a tether having a distal end and a proximal end; and

the distal end of the tether being attached to the tethering region on the expandable member and the proximal end of the tether being attached to the stent so that the expandable member resides within the patient'"'"'s stomach.

2. The space occupying device of claim 1 wherein the stent is configured for deployment in the patient'"'"'s esophagus.

3. The space occupying device of claim 1 wherein the stent is configured for deployment in the patient'"'"'s stomach.

4. The space occupying device of claim 1 wherein the stent is a self-expanding stent.

5. The space occupying device of claim 1 wherein the expandable member is inflatable.

6. The space occupying device of claim 1 wherein the distal end of the tether includes a swivel portion attached to the expandable member so that the expandable member is free to twist or rotate in the stomach without transmitting torsional forces to the stent.

7. The space occupying device of claim 1 wherein the stent is configured to be implanted in the patient'"'"'s pyloris.

8. A space occupying device for occupying a volume within a patient'"'"'s stomach, comprising:

an inflatable member having a tethering region adapted to reside within the patient'"'"'s stomach and occupy a volume therein when expanded;

an expandable stent; and

a tether having a distal end secured to the tethering region of the inflatable member and a proximal end attached to the expandable stent.
