<p><P>PROBLEM TO BE SOLVED: To prevent detachment of an X-ray opaque marker even while rich in flexibility. <P>SOLUTION: A shaft tube 42 includes an inner layer 31, a reinforcing layer 32, an outer layer 33, the X-ray opaque marker, and marker stoppers. The X-ray opaque marker stopper is positioned at least on one side of the tip side Ts and the end side Es with the X-ray opaque marker as a reference. The marker stopper is directly or indirectly fixed to the reinforcing layer 32. When the marker stopper is made of the same material as the reinforcing layer, the marker stopper can interpose between the reinforcing layer and the outer layer. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
