Abstract: A suction catheter for fragmenting and removing obstructive material and thrombus from the body or other body cavities that comprises a tube-like body with a proximal and distal end and a pressure lumen and discharge lumen formed in the catheter body. At the distal end of the catheter is a suction opening adjacent to the opening of the nozzle injector formation. At the proximal end of the catheter the lumens are connected to an inlet port and a discharge outlet. A hub structure is coupled to the proximal end of the catheter tubular body and includes a pressure lumen for connecting a fluid source to the pressure inlet. At the proximal end of the tubular catheter a discharge lumen is connected at the proximal hub to a discharge reservoir. The suction port at the distal end of the catheter may be formed into a separate lumen within the catheter body and may include a guidewire lumen.
