Abstract: In a method for inserting an endoscopic device, a guide wire is punctured into a subject from outside the body. A tip portion of the wire is inserted into a first hollow organ. A tip-side portion of the inserted wire is projected into a lumen of a second hollow organ that communicates with the first via an opening, from the opening. An endoscopic device is inserted through a flexible endoscope and pushed into the second hollow organ. A tip portion of the device is locked onto the tip-side portion of the wire projecting into the second hollow organ. A portion of the wire outside the body of the subject is held and is tugged outside of the body. The tip portion of the device is thus pulled into the first hollow organ from the second, via the opening. Therefore, the endoscopic device can be led to the first hollow organ.

Abstract: A stent delivery method includes: forming through-holes in an alimentary canal wall and a cyst wall so as to communicate with each other; passing a stent through the through-holes and placing a first expandable part in the alimentary canal and a second expandable part in the cyst; allowing the first expandable part to expand to an expanded state in the alimentary canal; and, after the expansion of the first expandable part, allowing the second expandable part to expand in the cyst while the alimentary canal wall is pressed by the first expandable part in the expanded state.

Abstract: A medical instrument is that the first holding portion or the second holding portion is capable of moving so that a distance between a distal end of the first holding portion and a distal end of the second holding portion changes from a first dimension which is larger than a diameter of the wire to a second dimension which is smaller than the diameter of the wire and the space is formed by the first holding portion and the second holding portion such that the wire is capable of rotating about a line connecting a first contact point where the first protrusion portion contacts with the wire with a second contact point where the second protrusion portion contacts with the wire.

Abstract: In a disclosed method for inserting an endoscopic device, in a state in which a guide wire is inserted through an opening of a hollow organ of a subject, the guide wire is indwelt in the hollow organ. Next, a flexible endoscope is made to approach the opening of the hollow organ. Next, inside of the body of the subject, an endoscopic device that projects from the tip of a channel of the endoscope slidably engages with the guide wire. Next, the endoscopic device is inserted into the hollow organ through the opening, along the guide wire. The guide wire that is indwelt once is subsequently used as a guide for second and subsequent insertions of endoscopic devices.
