A catheter assembly for the treatment of vessels carrying body fluid, comprises an inner catheter provided with a guide wire lumen (32) for receiving a guide wire (44) and an inflation lumen (30) for a balloon (26) provided at its distal end. The catheter assembly further comprises an outer catheter provided with an inflation lumen (30) for a balloon (14) provided at its distal end and a lumen (20) in which the inner catheter is applied shiftable for changing the spacing of the two balloons (14, 26) and which features a larger cross-section than that of the inner catheter so that between the outer wall of the inner catheter and the inner wall of the outer catheter a cross-section employable as an inflation lumen exists and ports into the portion sited between the two balloons (14, 26). The guide wire lumen (32) of the inner catheter is connected to the portion sited between the two balloons (14, 26) via ports (40) in the catheter wall. The guide wire lumen (32) is dimensioned cross- sectionally so that it can be used as the inflation lumen (30) also when the guide wire (44) is in the lying position, and the guide wire (44) is provided at its distal end with an occlusion element (46) for closing off the port (42) located at the distal end of the guide wire lumen (32).
