Abstract
A blood purification system comprised of a dialysis system for purifying a patient's blood and a dual-lumen catheter coupled to the dialysis system. The dual-lumen catheter is comprised of an elongated cylindrical tube having an internal diametral septum extending along the length thereof. The septum and the walls of the elongated cylindrical tube form at least three longitudinal lumens, the first and second of which have substantially semi-circular transverse cross-sections occupying the major portion of the transverse cross section of the interior of the tube, and the third lumen has a small transverse cross-section located at the intersection of one diametral end of the septum with the tube, between a pair of adjacent corners of the first and second lumens.
