Abstract

The catheter comprises at least one tubular basic body with a proximal and a distal end. On the distal end is arranged a filter element which is formed by a number of flexible strips which are distributed over the periphery and extend in longitudinal direction of the basic body and which are each curved substantially arcuately in outward direction and which can be pressed together elastically. The strips are formed by wall parts of the basic body defined between incisions of the basic body. The incisions extend helically.
