Abstract: An improvement over the Foley catheter which provides, in addition to the main drainage lumen, a central smaller lumen for continuous delivery of a small quantity of sterile irrigating solution directly through the distal tip into the bladder. A larger portion of the irrigating solution is deflected by the cone shaped roof of the distal tip and turned backward past the drainage ports and into the drainage lumen. This backward flow of liquid causes a mild suction which assists the removal of clots and tissue debris from the bladder. The continuous flow of sterile solution also cleanses the drainage lumen and prevents the upward movement of bacteria common in most urinary catheters. A suction syringe can also be used in the usual manner in the event of a blockage. A second embodiment of the invention provides two protuberances across from the drainage ports within the distal tip to assist in breaking up clots as they enter the drainage lumen.
