Obesity treatment tools and methods
First Claim
1. A method for reducing the volume of a stomach cavity, comprising:
- positioning a device trans-orally to a position within the stomach cavity;
acquiring tissue from the interior of the stomach cavity with the device; and
forming a pouch by securing the acquired tissue within the stomach cavity, the stomach cavity having a main volume, and the pouch having a pouch volume separate from and in communication with the main volume, wherein the pouch volume is substantially less than the main volume, and wherein the pouch accepts food from the esophagus.

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.

12. A method for reducing the volume of a stomach cavity, comprising:
-
positioning a device trans-orally to a position within the stomach cavity; acquiring tissue from at least two areas of the interior of the stomach cavity using the device, the stomach cavity defining a main volume; and fastening the at least two areas of the interior of the stomach cavity together using the device to form a pouch having a proximal end and a distal end within the stomach cavity, the pouch having a pouch volume separate from and in communication with the main volume; wherein the pouch volume is substantially less than the main volume; and wherein the pouch is in communication with the esophagus. - View Dependent Claims (13, 14, 15, 16, 17, 18)
