ABSTRACT:
A multiple-lumen catheter comprises an elongated cylindrical tube which has an internal diametral septum extending along the length thereof. This septum and the walls of the tube form at least three longitudinal lumens. The first and second lumens have substantially semi-circular transverse cross-sections which occupy the major portion of the transverse cross-section of the interior of the tube. A third lumen has a small transverse cross-section and is located at the intersection of one diametral end of the septum with the tube. This third lumen lies between a pair of adjacent corners of the first and second lumens.
