Title:

BODY INSERTION TUBE SELF-ADHERING TO TISSUE, AND METHOD FOR ADHERING BODY INSERTION TUBE TO BODY ORGAN TISSUE

Document Type and Number:

WIPO Patent Application WO/2013/172474

Kind Code:

A1

Abstract:

Provided are a body insertion tube capable of self-adhering to a tissue that is applicable to a combined low-energy adhesion method, and a method for adhering the aforesaid body insertion tube to a body organ tissue to thereby adhere the body insertion tube to the body organ tissue more quickly and easily than in conventional cases and establish a high adhesion strength without forming a gap that allows the invasion of bacteria. The body insertion tube according to the present invention, which is to be contacted with a body organ tissue and adhered thereto in a state of being coated with the aforesaid body organ tissue, is characterized in that, on the side of the body insertion tube to be in contact with the body organ tissue, at least a groove, hole or depressed part is formed, said groove, hole or depressed part having such a size as allowing a part of the body organ tissue to enter therein through deformation or displacement and thus achieve an anchoring effect, and a passage for applying a negative pressure to the groove, hole or depressed part, upon the adhesion of the body insertion tube to the body organ tissue, is also formed.
