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 marking device for marking a location on an interior surface

within an organ comprising:

an elongate member having a proximal end and a distal end with a length therebetween, the length defining a shape which approximates a lumen to be formed from the interior surface, at least one dye port being formed through a sidewall of the elongate member, and at least one vacuum port being formed through the sidewall of the elongate member, the at least one dye port being configured to contact an area of the interior surface and deliver dye, and the at least one vacuum port being configured to remove air and fluid from within the organ when the at least one vacuum port is located therein

wherein the at least one dye port comprises a plurality of dye ports and the at least one vacuum port comprises a plurality of vacuum ports, a first number of the plurality of vacuum ports being positioned on one side of the plurality of dye ports, and a remaining number of the vacuum ports being positioned on another side of the plurality of dye ports.

2. The marking device of claim 1, further comprising an inflatable balloon at the distal end of the elongate member.

3. The marking device of claim 1, wherein a plurality of additional dye ports are formed through the sidewall of the elongate member.

4. The marking device of claim 1, wherein the organ comprises a stomach.

5. The marking device of claim 1, wherein the elongate member is curved.

6. The marking device of claim 5, wherein the curved elongate member is configured to follow a lesser curvature of a stomach.

7. The marking device of claim 5, wherein the at least one dye port is defined along an outer radius of curvature of the curved elongate member.

8. The marking device of claim 1, wherein the elongate member is configured to be delivered to the interior surface trans-esophageally.

9. The marking device of claim 1, wherein a plurality of additional vacuum ports are formed through the sidewall of the elongate member.

10. The marking device of claim 1, wherein the at least one vacuum port is positioned adjacent to the at least one dye port such that the at least one vacuum port is configured to remove air and fluid from within the organ without interfering with delivery of the dye from the at least one dye port.

11. The marking device of claim 1, wherein the plurality of dye ports are linearly aligned along a longitudinal length of the elongate member.
