[57] ABSTRACT

A drainage catheter for selective positioning within the human vasculature which includes a catheter body defining separate pressure and discharge lumens. A connector means at a proximal end ol the catheter connects the pressure channel to a source ol liquid under pressure. An inlet opening is positioned in the side ol the catheter adjacent the distal end thereol and communicates with the discharge channel. The pressure channel extends Irom the proximal end distally forward ol the inlet opening and then curves rearwardly to join the discharge channel at said inlet opening. The pressure channel is shaped to form a spray nozzle to direct pressurized fluid in the pressure channel across said inlet opening and into the discharge channel to create a suction adjacent the inlet opening. A preformed distal tip portion extends from the distal end ol the drainage catheter. The preformed tip portion is formed ol a material having the characteristic ol retaining a plastic memory and is preformed into a curved configuration for selective positioning.
