## Abstract

This gastric therapy system includes a loop-forming member that forms a loop along a lesser-curvature-line and a greater-curvature-line in a stomach; a guide member that introduces the loop-forming member into the stomach; and a therapy section that cerclages a part of the gastric wall after looping the loop-forming member.

## Claims

### Claim 1

A method for cerclaging a gastric wall comprising:
inserting a flexible elongated loop-forming member perorally into a stomach and advancing the loop-forming member along a lesser-curvature-line;
returning the loop-forming member at a position closer to an oral side than a pyloric antrum of the stomach, advancing the loop-forming member along a greater-curvature-line, and forming a loop in the stomach;
suctioning air from the stomach after looping the loop-forming member in the stomach, and shrinking the stomach so that an anterior gastric wall is in proximity with a posterior gastric wall within the looped loop-forming member; and
cerclaging the anterior gastric wall and the posterior gastric wall that are in proximity by shrinking the stomach.

### Claim 2 (depends on 1)

The method for cerclaging the gastric wall according to claim 1, wherein a suture thread is punctured alternately through the anterior wall and the posterior wall while rotating a bent needle when the anterior gastric wall and the posterior gastric wall are cerclaged.

### Claim 3 (depends on 1)

The method for cerclaging the gastric wall according to claim 1, including dissecting mucosa of tissues that should be adheded after the cerclage before cerclaging the anterior gastric wall and the posterior gastric wall.

### Claim 4 (depends on 1)

The method for cerclaging the gastric wall according to claim 1, including embedding an implant into the gastric wall after cerclaging the anterior gastric wall and the posterior gastric wall.

### Claim 5 (depends on 4)

The method for cerclaging the gastric wall according to claim 4, wherein a position for embedding the implant is an entrance in the vicinity of a cardia of the stomach of a section that is cerclaged; an exit in the vicinity of the pylorus of the stomach; or a whole length or a part of the section that is cerclaged.

### Claim 6 (depends on 4)

The method for cerclaging the gastric wall according to claim 4, wherein the implant is a metal or resin coil, or a suture thread.

### Claim 7 (depends on 2)

The method for cerclaging the gastric wall according to claim 2, further comprising:
measuring thicknesses of a mucosa and a muscle coat of the gastric wall that should be cerclaged before or after inserting a cerclage instrument that cerclages the anterior gastric wall and the posterior gastric wall;
selecting the cerclage instrument suitable for the measured thicknesses of the mucosa and the muscle coat, and cerclaging the mucosa of the gastric wall by using the cerclage instrument.

### Claim 8 (depends on 7)

The method for cerclaging the gastric wall according to claim 7, wherein the thicknesses of the mucosa and the muscle coat of the gastric wall are measured by using an ultrasonic endoscope or an ultrasonic searcher attached to the cerclage instrument.

### Claim 9 (depends on 2)

The method for cerclaging the gastric wall according to claim 2, further comprising:
measuring thicknesses of a mucosa and a muscle coat of the gastric wall that should be cerclaged before or after inserting a cerclage instrument that cerclages the anterior gastric wall and the posterior gastric wall; and
adjusting the cerclage instrument based on the measured thicknesses of the mucosa and the muscle coat, and cerclaging the mucosa of the stomach by using the cerclage instrument.

### Claim 10 (depends on 9)

The method for cerclaging the gastric wall according to claim 9, wherein the thicknesses of the mucosa and the muscle coat of the gastric wall are measured by using an ultrasonic endoscope or an ultrasonic searcher attached to the cerclage instrument.
