9. A method for positioning an indwelling tube comprising:
-
detachably mounting a guide catheter fixing member to a distal end portion of an elongate insertion part inserted into the body cavity;
fixing and holding a distal end portion of a guide catheter along the axial direction of said insertion part to said guide catheter fixing member;
inserting said insertion part into a body cavity to a targeted position, while the distal end portion of said guide catheter is fixedly held;
withdrawing the distal end portion of said guide catheter from said guide catheter fixing member;
inserting a guide wire into said guide catheter to permit the end of said guide wire to protrude from the distal end of said guide catheter;
permitting the end of said guide wire to reach said targeted position, while said guide catheter is pulled out of the body cavity; and
inserting said indwelling tube along said guide wire from the outside of the body cavity to said targeted position to position said indwelling tube at said targeted position inside the body cavity; and
withdrawing said insertion part out of the body cavity.
