Abstract

A gastric space filler device for treating obesity in a patient by reducing the stomach volume comprising at least one inflatable space filler and a pressure sensor secured to the space filler, wherein the pressure sensor yields a noticeable signal for causing removal of the space filler.

Claims

1. A double-balloon intragastric space filler for treating obesity in a patient by reducing the stomach volume, comprising a proximal inflatable balloon secured to a distal inflatable balloon by an elongate fluid infusing member having a first lumen and a second lumen, wherein said first lumen has a first slit for fluid communication with the proximal balloon and said second lumen has a second slit for fluid communication with the distal balloon.

2. The intragastric space filler of claim 1, further comprising at least one radiopaque marking.

3. The intragastric space filler of claim 2, wherein the at least one radiopaque marking is located at a proximal end of the elongate fluid infusing member.

4. The intragastric space filler of claim 3, further comprising a retrieval loop located at about the at least one radiopaque marking configured for coupling to a retrieval catheter.

5. The intragastric space filler of claim 4, wherein the retrieval loop has a diameter of between about 1 and 10 mm.

6. The intragastric space filler of claim 4, wherein the loop is located in a recessed zone but accessible to the retrieval catheter when the proximal balloon is substantially inflated.

7. The intragastric space filler of claim 2, further comprising a radiopaque marking located at a distal end of the elongate fluid infusing member.

8. The intragastric space filler of claim 1, wherein the proximal balloon is substantially larger than the distal balloon.

9. The intragastric space filler of claim 1, wherein an overall axial length of the double-balloon space filler is between about 100 and 300 mm.

10. The intragastric space filler of claim 1, wherein an overall axial length of the double-balloon space filler is between about 150 and 200 mm.

11. The intragastric space filler of claim 1, wherein a balloon wall thickness is between about 0.2 and 1.0 mm.

12. The intragastric space filler of claim 1, wherein a balloon wall thickness is between about 0.3 to 0.5 mm.

13. The intragastric space filler of claim 1, wherein a distance between the two balloons is between about 10 to 40 mm.

14. The intragastric space filler of claim 1, wherein a distance between the two balloons is between about 20 and 30 mm.

15. The intragastric space filler of claim 1, wherein the fluid infusing member has an inner diameter of between about 1 and 6 mm.

16. The intragastric space filler of claim 1, wherein the fluid infusing member has an inner diameter of between about 3 and 5 mm.

17. The intragastric space filler of claim 1, wherein a wall thickness of the fluid infusing member is between about 0.2 and 2 mm.

18. The intragastric space filler of claim 1, wherein a wall thickness of the fluid infusing member is between about 0.5 and 1.5 mm.

19. The intragastric space filler of claim 1, wherein the proximal balloon is expandable to a space volume of between about 100 and 600 cc.

20. The intragastric space filler of claim 1, wherein the proximal balloon is expandable to a space volume of between about 300 and 500 cc.
