Abstract

The invention concerns a catheter (12) which is connected to a rotary drive (20) and has at its front end (12a) a cutting tool comprising a stator (14) and rotor (16). Peripheral blades of the rotor (16) and stator (14) co-operate in scissors-like manner. The detached deposits are conveyed through a tubular casing (22), via a discharge chamber (18), into a collection container (28). The conveying device is a drive shaft which takes the form of a feed screw, is disposed inside the tubular casing (22) and connects the rotary drive (20) to the rotor (16). A rotary catheter of this type is used for gentling removing and discharging thrombi and stenoses in narrowed blood vessels such as arteries and veins.
