<p>A catheter (10) comprises: a rotationally operable section (62) which moves an outer tube body (16) in the axial direction thereof relative to an inner tube body (14); and a stopper section (116) which, while a closing section (40) provided at the distal end section of the inner tube body (14) is separated from the outer tube body (16) and the distal end opening (38) of the outer tube body (16) is open, limits the rotational movement of the rotationally operable section (62) so that the outer tube body (16) is prevented from moving to at least the distal end side relative to the inner tube body (14).</p> |
