PCT No. PCT/CH96/00086 Sec. 371 Date Sep. 29, 1997 Sec. 102(e) Date Sep. 29, 1997 PCT Filed Mar. 7, 1996 PCT Pub. No. WO96/29942 PCT Pub. Date Oct. 3, 1996The catheter connected to a rotary drive mechanism 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 detached deposits are conveyed through a tubular sheath and into a collection container via a discharge chamber. A drive shaft which is arranged inside the tubular sheath, and which connects the rotary drive mechanism to the rotor, is designed as a conveyor screw and is used for the conveying. A rotary catheter of this kind is used for carefully removing and withdrawing blood clots and stenoses from narrowed blood. |
