<p><P>PROBLEM TO BE SOLVED: To provide a delivery device for a tubular organ treatment instrument with which the degree of opening of a tubular organ treatment instrument is reliably confirmed. <P>SOLUTION: The delivery device 10 includes an outer tube 20 and an inner tube 30 disposed in the outer tube 20. The inner tube 30, which is formed to be longer than the outer tube 20 and extends from the proximal end part of the outer tube 20, has indexes 70 formed to confirm a sliding position of the outer tube 20 relative to the inner tube 30 at the part extending from the proximal end part of the outer tube 20 on the inner tube 30. When the outer tube 30 slides to the proximal end side relative to the inner tube 30 while the tubular organ treatment instrument 5 is retained by a retaining part 60, the instrument 5 is opened. Then, the amount of the opening of the instrument 5 is confirmed since the amount of sliding of the outer tube 20 relative to the inner tube 30 is confirmed by using the index 70 as the criterion. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
