Organ anastomosing apparatus and method

An organ anastomosing method comprising the steps of:

• preparing a pair of magnets, including a first and a second magnet and having a plurality of adsorption surfaces on each of the first and second magnets, to at least one of which a flexible guide wire is detachably mounted, guide tube to be disposed to come into contact with a guide wire mount surface of the first magnet and a cylindrical sheath to guide the guide wire;
• disposing the second magnet at a predetermined site of one of organ walls of a subject to be anastomosed to each other;
• inserting the cylindrical sheath from an outside of a subject into a body of the subject;
• inserting the first magnet for detachably mounting the flexible guide wire into the sheath and inserting the magnet into the other one of the organ walls to dispose the magnet at a predetermined site, the organ being adsorbed by said first magnet to said second magnet, thereby pinching a portion of the organ wall;
• forming a through hole to establish a communication between the organ walls by pinching the organ walls and forming an anastomosis around the through hole;
• removing the guide wire from the first magnet by pulling the guide wire towards the outside of a body of the subject when said guide tube is inserted into said sheath to support a tip end of the guide tube in contact with a guide wire mount surface of said first magnet;
• leaving the guide tube for a predetermined period of time while inserting the guide tube into the through hole of the anastomosis site;
• and
• pulling out the guide tube from the anastomosis site and the subject's body after an elapse of the predetermined period of time,
• wherein the plurality of adsorption surfaces on each of the first and second magnets includes a first surface having a first pole and a second surface having a second pole that is different from the first pole.
