Abstract
A triple catheter for removing of blood clots from arteries and veins is equipped with an outer catheter (1) that can be inserted into a blood vessel and an inner catheter (5) with an inflatable baloon (6) at its distal end that can be inserted into the outer catheter (1). The inner catheter (5) is surrounded by an intermediate catheter (2) also inserted into the outer catheter (1). The intermediate catheter (2) has a radially expandable distal end receptacle (3) made of an elastic mesh structure of spring wires or plastic monofilaments covered by or embedded in an elastic plastic coating. A very small puncture channel is required for the insertion of such a triple catheter through the wall of a blood vessel.
