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 device for forming a pouch within an interior of an organ, comprising:

a delivery member having a proximal end and a distal end;

a curved tube attached to the distal end of the delivery member, the curved tube having a lumen, and having a first releasably adhering section and a second releasably adhering section;

a septum removably attached to the curved tube to separate the first releasably adhering section from the second releasably adhering section; and

a fastener disposed within the lumen of the curved tube;

wherein the first and second releasably adhering section of the curve tube position a first area of the interior in apposition with a second area of the interior, and wherein the fastener is deployed from the curved tube to fix the first area of the interior with the second area of the interior to form the pouch.

2. The device of claim 1, wherein the curved tube is C-shaped, U-shaped, or crescent shaped.

3. The device of claim 1, wherein the first and second releasably adhering sections of the curved tube include vacuum ports separated by the septum.

4. The device of claim 1, wherein the first and second releasably adhering sections of the curved tube include a channel separated by the septum and a slot disposed within the channel being in communication with a vacuum.

5. The device of claim 4, wherein the fastener may be fired though the slot and into the first and second areas of the interior.

6. The device of claim 1, wherein the fastener is a staple.

7. The device of claim 6, wherein the staple includes a pivot.

8. The device of claim 7, wherein the staple is W-shaped.

9. The device of claim 1, further including a wedge slidingly positioned within the lumen of the curved tube, the wedge being adapted to urge the fastener from an open first configuration to a closed second configuration.

10. The device of claim 9, wherein the wedge further being adapted to push the septum along the curved tube.

11. The device of claim 1, wherein the fastener is a staple.

12. The device of claim 11, wherein the staple includes a pivot.
