Abstract

A method of cholecystitis treatment according to an aspect of the present disclosure comprises a step A including contacting inner walls of a gallbladder to each other by constricting the gallbladder and a step B including maintaining the inner walls of the gallbladder contacting each other.

First claim

What is claimed is:

1 . A method of cholecystitis treatment, comprising:
a step A including contacting inner walls of a gallbladder to each other by constricting the gallbladder; and a step B including maintaining the inner walls of the gallbladder contacting to each other.

2 . The method of cholecystitis treatment according to claim 1 , wherein the step A includes applying a negative pressure to an inner volume of the gallbladder.

3 . The method of cholecystitis treatment according to claim 1 , wherein the step A includes suturing the gallbladder using a thread.

4 . The method of cholecystitis treatment according to claim 1 , wherein the step B includes adhering the inner walls to each other.

5 . The method of cholecystitis treatment according to claim 1 , the method further comprising removing a content from the gallbladder before the step A.

6 . The method of cholecystitis treatment according to claim 1 , the method further comprising damaging an inner mucosa membrane of the gallbladder before the step A.

7 . The method of cholecystitis treatment according to claim 6 , wherein damaging the inner mucosa membrane includes spraying a chemical onto the inner mucosa membrane by using a catheter inserted into the gallbladder.

8 . The method of cholecystitis treatment according to claim 6 , wherein damaging the inner mucosa membrane includes ablating the inner mucosa membrane with a laser of a laser irradiation device inserted into the gallbladder.

9 . The method of cholecystitis treatment according to claim 1 , wherein contacting inner walls of the gallbladder to each other in step A includes contacting the inner walls sequentially from a cervical of the gallbladder to a bottom of the gallbladder.

10 . The method of cholecystitis treatment according to claim 1 , wherein contacting inner walls of the gallbladder to each other in step A includes contacting the inner walls sequentially from a bottom of the gallbladder to a cervical of the gallbladder.

11 . The method of cholecystitis treatment according to claim 1 , wherein contacting inner walls of the gallbladder to each other in step A includes contacting the internal walls of a body of the gallbladder after contacting the inner walls of a cervical of the gallbladder and contacting the inner walls of a bottom of the gallbladder.

12 . A treatment method, comprising:
a step A including contacting inner walls of an organ to each other; and a step B including maintaining the inner walls of the organ contacting to each other.

13 . The treatment method according to claim 12 , wherein the step A includes applying a negative pressure to an inner volume of the organ.

14 . The treatment method according to claim 12 , wherein the step A includes suturing the organ using a thread.

15 . The treatment method according to claim 12 , wherein the step B includes adhering the inner walls to each other.

16 . The treatment method according to claim 12 , the method further comprising removing a content from the organ.

17 . The treatment method according to claim 12 , the method further comprising damaging an inner mucosa membrane of the organ before the step A.

18 . The treatment method according to claim 17 , wherein damaging the inner mucosa membrane includes spraying a chemical onto the inner mucosa membrane by using a catheter inserted into the organ.

19 . The treatment method according to claim 17 , wherein damaging the inner mucosa membrane includes ablating the inner mucosa membrane with a laser of a laser irradiation device inserted into the sac-like organ.

20 . The treatment method according to claim 12 , wherein contacting inner walls of the organ to each other in step A includes contacting the inner walls sequentially from an opening of the organ to a bottom of the organ.

21 . The treatment method according to claim 12 , wherein contacting inner walls of the organ to each other in step A includes contacting the inner walls of the organ sequentially from a bottom of the organ to an opening of the organ.
