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 side-to-side anastomosis device for coupling adjacent regions of digestive tract, the anastomosis device, comprising.

a distal segment and a proximal segment, the distal and the proximal segments each being adapted to align in apposition with each other while maintaining the regions of digestive tract therebetween;

and

a deployment device comprising an elongate tubular member having a proximal end and a distal end with a lumen defined therebetween, the distal end being specially adapted to retain the proximal segment for alignment in apposition with the distal segment.

2. The anastomosis device of claim 1, wherein the distal and the proximal segments are magnetically coupled together while maintaining the regions of digestive tract therebetween.

3. The anastomosis device of claim 1, wherein the distal and the proximal segments are further coupled by mechanical fasteners.

4. The anastomosis device of claim 1, wherein the mechanical fasteners arc selected from the group consisting of grommet-type swages, snap lock fits, staples, screws, clips, and friction-fittings.

5. The anastomosis device of claim 1, wherein the deployment device further comprises a coring ring in the distal end, the coring ring being adapted to pass through a center of the distal segment and the proximal segment for removal of the regions of digestive tract therebetween.

6. The anastomosis device of claim 1, wherein the deployment device distal end is adapted to be manipulatable via the proximal end.

7. The anastomosis device of claim 1, further comprising a locating device adapted to urge the distal segment into a predetermined location in the digestive tract.

8. The anastomosis device of claim 7, wherein the locating device comprises a magnetized device selected from the group consisting of magnetic wands and magnetic pickups.

9. A system for organ volume reduction, comprising:

a device for insertion into all organ, the device being adapted to draw up a portion of an interior of the organ;

a fastening device adapted to fasten the portion of interior; and

a side-to-side anastomosis device for coupling adjacent regions of digestive tract, the anastomosis device including a distal segment and a proximal segment, the distal and the proximal segments each being adapted to align in apposition with each other while maintaining the regions of digestive tract therebetween.

10. The system of claim 9, wherein the device for insertion is inserted into the organ endoscopically via an esophageal passageway.

11. The system of claim 9, wherein the anastomosis device is inserted into the digestive tract endoscopically via an esophageal passageway.

12. The system of claim 9, wherein the anastomosis device is inserted into the digestive tract laparoscopically.

13. A method for gastric reduction, comprising:

creating a first side-to-side anastomosis between a first portion of digestive tract and a gastric pouch using an anastomosis device;

creating a second side-to-side anastomosis between a second portion of digestive tract and a third portion of digestive tract using the anastomosis device; and

creating a separate gastric lumen within the gastric pouch using a fastening device.

14. The method of claim 13, wherein the first portion of digestive tract comprises a predetermined section selected from the group consisting of duodenum and jejunum.

15. The method of claim 13, wherein the second portion of digestive tract comprises a predetermined section of duodenum.

16. The method of claim 13, wherein the third portion of digestive tract comprises a predetermined section of ileum.

17. The method of claim 13, wherein creating a second side-to-side anastomosis further comprises closing off a section of digestive tract disposed intermediate of the first portion and the second portion.

18. The method of claim 17 wherein the section of digestive tract disposed intermediate of the first portion and the second portion comprises duodenum.

19. The method of claim 13, wherein the first anastomosis is located about 20 to 50 cm from a pylorus of the gastric pouch.

20. The method of claim 13, wherein the second anastomosis is located about 15 to 55 cm from the pylorus of the gastric pouch.

21. The method of claim 13, wherein the second anastomosis is located about 150 to 200 cm along the digestive tract from the pylorus of the gastric pouch.
