A suction catheter has a tubular body with a distal end, a proximal end, and an inlet lumen and a discharge lumen formed in the catheter body. At the distal end of the catheter, the inlet lumen is connected with a nozzle, and the discharge lumen opens into a suction inlet. At the proximal end of the catheter, the lumens are connected to a proximal hub having an inlet port and a discharge port. The inlet lumen may be formed in a separate tube received inside the catheter body, and the suction catheter may include a guidewire lumen adapted to receive a guidewire.
