Abstract
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 can be formed by a number of strip-shaped wall sections of the basic body defined in between longitudinal cuts evenly distributed around the circumference and may furthermore comprise 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.
Claims5
Catheter comprising:
- a tube-like catheter body with a distal and a proximal end connected by a longitudinal section, wherein the catheter comprises at the distal end an expandable filter element;
- and
- further contained at the distal end, a device for reducing thrombi in size and removing them;
- and
- wherein the filter element is formed by a number of strip-shaped wall sections of of the tube-like catheter body defined in between longitudinal cuts evenly distributed around the circumference;
- and furthermore comprising a means for moving sections of the tube-like catheter body, said means for moving situated on the distal end and causing certain of the wall sections to move towards each other in order to make other parts of the wall sections bend outwards;
- and
- wherein the device for reducing thrombi comprises a jet nozzle connected to a pressure lumen and a discharge opening connected to a discharge lumen, said device situated inside the tube-like catheter body such that said jet nozzle is pointing in the proximal direction and said discharge opening is proximal of said jet nozzle.
