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;

wherein the distal segment is separate from the deployment device and is configured to be selectively coupled to and removed from the deployment device;

wherein the distal segment includes a coring anvil extending proximally therefrom, the coring anvil being configured to extend into a cavity formed in a distal portion of the proximal 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. The anastomosis device of claim 1, wherein the distal segment is configured to be movable with a magnetic device from outside a body of a patient including the digestive track without the magnetic device moving the proximal segment within the body of the patient.

10. A side-to-side anastomosis device, comprising:

a distal segment and a proximal segment, the distal and the proximal segments being configured to mate together while maintaining adjacent regions of a 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 of the deployment device being configured to mate with the proximal segment;

wherein the distal segment is detachable from the proximal segment such that the distal segment is configured to be inserted into a body of a patient independent of the deployment device and independent of the proximal segment;

wherein the distal segment includes a coring anvil extending proximally therefrom, the coring anvil being configured to extend into a cavity formed in a distal portion of the proximal segment.

11. The anastomosis device of claim 10, wherein the distal and the proximal segments are configured to be magnetically coupled together to maintain regions of digestive tract therebetween.

12. The anastomosis device of claim 10, further comprising a locating device configured to urge the distal segment into a predetermined location in the digestive tract.

13. The anastomosis device of claim 12, wherein the locating device comprises a magnetic device selected from the group consisting of magnetic wands and magnetic pickups.

14. The anastomosis device of claim 10, wherein the distal segment is magnetized and is configured to be moved within the body of the patient from outside the body of the patient using a magnetic device.

15. The anastomosis device of claim 14, wherein the distal segment is configured to be movable within the body of the patient from outside the body of the patient using the magnetic device without the magnetic device moving the proximal segment within the body of the patient.

16. The anastomosis device of claim 10, wherein the distal end of the deployment device having the proximal segment mated thereto is configured to be inserted into the body of the patient, thereby inserting the proximal segment into the body of the patient.

17. The anastomosis device of claim 16, wherein the distal end of the deployment device having the proximal segment mated thereto is configured to be inserted into the body of the patient without the distal segment being coupled to the proximal segment.
