Abstract

Various obesity treatment tools and methods are described herein, as well as treatments for other gastric-related diseases, e.g., GERD. Treatment includes reducing the size of the stomach pouch to limit the caloric intake as well as to provide an earlier feeling of satiety. This may be done by creating a smaller gastric pouch within the stomach directly from the interior of the stomach itself. The smaller pouches may be made through the use of individual anchoring devices, rotating probes, or volume reduction devices. A pyloroplasty procedure may also be performed to render the pyloric sphincter incompetent. A gastric bypass procedure may additionally be performed using atraumatic magnetic anastomoses devices so that sugars and fats are passed directly to the bowel while bypassing the stomach. Many of these procedures may be done in a variety of combinations. Treatment may create enforced behavioral modifications by discouraging the ingestion of high-caloric foods.

Claims

1. A gastric pouch, comprising:

a main lumen having an exterior surface and an interior surface; and

a pouch lumen having a proximal end and a distal end formed from an internally approximated portion of the interior surface such that the pouch lumen defines a volume separate from and in communication with, the main lumen.

2. The gastric pouch of claim 1 further comprising a plurality of fasteners attached to a junction defined by the pouch lumen and the main lumen.

3. The gastric pouch of claim 2 wherein the fasteners comprise biocompatible mechanical fasteners selected from the group consisting of staples, tags, clips, sutures, screws, and adhesives.

4. The gastric pouch of claim 1 wherein the pouch lumen is defined via a longitudinal partition.

5. The gastric pouch of claim 1 wherein the pouch lumen is tapered such that the distal end is larger than the proximal end.

6. The gastric pouch of claim 1 wherein the pouch lumen is tapered such that the proximal end is larger than the distal end.

7. The gastric pouch of claim 1 wherein the pouch lumen volume is less than a volume defined by the main lumen.

8. The gastric pouch of claim 1 wherein the pouch lumen volume and a main lumen volume are unequal.

9. The gastric pouch of claim 1 wherein the pouch lumen is coaxially positioned within the main lumen.

10. The gastric pouch of claim 1 wherein the pouch lumen is adjacent to the main lumen.

11. The gastric pouch of claim 1 wherein the pouch lumen is in communication with an esophagus.

12. The gastric pouch of claim 1 wherein the approximated portion of the interior surface includes at least a portion of exterior surface.

13. The gastric pouch of claim 1 wherein the approximated portion of the interior surface includes at least a portion of an interior lining.

14. The gastric pouch of claim 1 wherein the approximated portion of the interior surface includes at least two layers of gastric tissue.

15. A gastric pouch within a hollow body organ, the pouch comprising:

a pouch lumen having a proximal end and a distal end and an interior tissue surface, said pouch further formed by approximating the interior tissue surface from within the hollow body organ,

wherein the pouch lumen defines a volume separate from and in communication with a main volume of the hollow body organ.

16. The gastric pouch of claim 15 wherein the pouch lumen is in communication with an esophagus.

17. The gastric pouch of claim 15 further comprising a plurality of fasteners attached to the interior tissue surface defining the pouch lumen.

18. The gastric pouch of claim 17 wherein the fasteners comprise biocompatible mechanical fasteners selected from the group consisting of staples, tags, clips, sutures, screws, and adhesives.

19. The gastric pouch of claim 15 wherein the pouch lumen is defined via a longitudinal partition.

20. The gastric pouch of claim 15 wherein the pouch lumen is tapered such that the distal end is larger than the proximal end.

21. The gastric pouch of claim 15 wherein the pouch lumen is tapered such that the proximal end is larger than the distal end.

22. The gastric pouch of claim 15 wherein the pouch lumen volume is less than the main lumen volume.

23. The gastric pouch of claim 15 wherein the pouch lumen volume and the main lumen volume are unequal.

24. The gastric pouch of claim 15 wherein the pouch lumen is coaxially positioned within the hollow body organ.

25. The gastric pouch of claim 15 wherein the pouch lumen is adjacent to the hollow body organ volume.

26. The gastric pouch of claim 15 wherein the approximated interior tissue surface includes at least two layers of gastric tissue.

27. A gastric pouch within a stomach, the pouch comprising:

a pouch lumen having a proximal end and a distal end and an interior tissue surface, the pouch being formed by approximating the interior tissue surface trans-esophageally,

wherein the pouch lumen defines a volume separate from and in communication with a main volume of the stomach.

28. The gastric pouch of claim 27 wherein the pouch lumen is in communication with an esophagus.

29. The gastric pouch of claim 27 wherein the pouch lumen is formed using an endoscope.

30. The gastric pouch of claim 27 wherein the pouch lumen is defined via a longitudinal partition.

31. The gastric pouch of claim 27 wherein the pouch lumen is tapered such that the distal end is larger than the proximal end.

32. The gastric pouch of claim 27 wherein the pouch lumen is tapered such that the proximal end is larger than the distal end.

33. The gastric pouch of claim 27 wherein the pouch lumen volume is less than the main lumen volume.

34. The gastric pouch of claim 27 wherein the pouch lumen volume and the main lumen volume are unequal.

35. The gastric pouch of claim 27 wherein the pouch lumen is coaxially positioned within the stomach.

36. The gastric pouch of claim 27 wherein the pouch lumen is adjacent to the stomach volume.

37. The gastric pouch of claim 27 wherein the approximated interior tissue surface includes at least two layers of gastric tissue.

38. A gastric pouch, comprising:

a main lumen having an interior surface having defined portions; and

a pouch lumen having a proximal end and a distal end formed from approximating and fastening at least three portions of the interior surface such that the pouch lumen defines a volume separate from and in communication with the main lumen.

39. The gastric pouch of claim 38 further comprising a fourth portion.

40. The gastric pouch of claim 38 wherein the approximated portions further include at least a portion of exterior surface.

41. The gastric pouch of claim 38 further comprising a plurality of fasteners attached to a junction defined by the pouch lumen and the main lumen.

42. The gastric pouch of claim 41 wherein the fasteners comprise biocompatible mechanical fasteners selected from the group consisting of staples, tags, clips, sutures, screws, and adhesives.

43. The gastric pouch of claim 38 wherein the pouch lumen is defined via a longitudinal partition.

44. The gastric pouch of claim 38 wherein the pouch lumen is tapered such that the distal end is larger than the proximal end.

45. The gastric pouch of claim 38 wherein the pouch lumen is tapered such that the proximal end is larger than the distal end.

46. The gastric pouch of claim 38 wherein the pouch lumen volume is less than a volume defined by the main lumen.

47. The gastric pouch of claim 38 wherein the pouch lumen volume and a main lumen volume are unequal.
