Abstract

A catheter provided with a shaft having a proximal and distal end, and provided with a stenosis-removing part located near the distal end of the shaft, wherein the stenosis-removing part can be brought into a first position and a second position, wherein, in a first position, the stenosis removing part extends substantially inside the circumferential contours of the shaft, wherein, in a second position, the stenosis-removing part extends outside the circumferential contours of the shaft, so that a radial outside of the stenosis removing part is at a greater radial distance from the center line of the shaft than in the first position, wherein an actuator assembly is provided for making the stenosis-removing part vibrate at a high frequency. The stenosis-removing part can be provided with hairs or may comprise a gauze shaped member of which the distal part has a finer mesh than the proximal part for filtering purposes.
