The invention relates to a filter catheter for partially and at least temporarily interrupting a blood vessel. This filter comprises an external angular element with a distal end and a proximal end, where are placed at its distal end, symmetrically distributed over the periphery, longitudinal notches delimiting flexible bands, taken in a lumen of the external angular element an element internal anguiform with a distal end and a proximal end, where the external angular element and the internal angular element are connected at their distal ends. Between the lumen of the external angular element and the internal angular element, a conduit has formed which is in communication with the filter element. |
