ABSTRACT:
A catheter device having, in coaxial arrangement, an insertion catheter, a dilation catheter and an occlusion catheter. By means of the occlusion catheter a vessel carrying body fluid is closed off in the direction of flow following a stricture. By means of the dilation catheter, the stricture is treated by dilation. The occlusion catheter positioned beyond the stricture prevents an embolism due to detached particles flowing off. After treatment of the stenosis, vessel fluid together with any detached particles is removed by suction and washed out through the insertion catheter.
