Zusammenfassung:Systems, devices, and processes for aspirating, fragmenting and extracting removable material from hollow bodies. A guide wire (11) is inserted into the hollow body (1) via an opening. Material is removed by means of a reducing catheter (3) having a working head (6) with stator (8) and rotor (9) that is connected to a feed screw (10). The stator (8) has a lateral inlet opening (8a) which is formed as two circular holes arranged in axial succession. Material forced into the inlet openings (8a) is sheared and/or fragmented. A flexible sleeve (7) serves to discharge the ablated material. Prior to this, a sheathing catheter (4) is inserted into the hollow body (1) until in front of the material to be removed. The cross-section of the hollow body (1) is occluded by the sheathing catheter (4), preventing detached fragments from being accidentally washed away.
