Zusammenfassung:The invention refers to a catheter (51) for aspiration, fragmentation and removal of removable material from blood vessels. The catheter (51) comprises a flexible tube (52), a flexible helical transport screw (62) inside of the flexible tube (52), a stopper element (82) for providing an abutment for the distal end (64) of the flexible helical transport screw (62). The stopper element (82) is provided spaced from the distal end of the catheter (51), thereby defining a distal region (56) of the catheter (51) extending from the stopper element (82) in direction to the distal end of the catheter (51) which is free of rotational elements inside. A suction opening (74) for aspiration of the removable material into the inside of the flexible tube (52) is provided in the distal region (56) of the catheter (51).
