A gripper-like basket 5 is arranged on the terminal section 3, to be inserted in the ureter, of the guide member designed as a Bowden pull wire 2, hose or the like. The gripping members 6 of this basket 5 can be pivoted between a closed position 8 and a spread position 9 in the direction of advance by means of an adjustment device 7. The adjustment device 7 is connected to the thread 10 mounted in the Bowden pull wire 2. A fixing device 12 is located on the terminal section 11 of the Bowden pull wire 2 facing away from the basket 5. A measuring device 15 for adjustment of the opening angle of the basket 5 is formed in the region of the fixing device 12. <IMAGE>
