Date Oct. 3, 1996The catheter connected to a drive unit has, at its front end a cutting tool which consists of a stator and rotor. Cutting edges arranged on the circumference of the rotor and stator interact in a shearing action. The rotor is an external rotor. The detached deposits are conveyed through a tubular sheath and into a collecting container via a discharge chamber. A rotary catheter of this kind is used for carefully removing blood clots and stenoses from narrowed blood vessels such as arteries and veins.
