Catheter with filter and thrombidischarge device

摘要

This invention relates to a catheter comprising a tube-like basic body with a distal and a proximal end, wherein the catheter comprises an expandable filter element at the distal end and a device for reducing thrombi in size and removing them. The filter element is formed by a number of strip-shaped wall sections of the basic body defined in between longitudinal cuts evenly distributed around the circumference and furthermore comprises a means for moving the sections of the basic body positioned on either side of the wall sections towards each other in order to make the wall sections bend outwards.
