ABSTRACT:
A single or multiple lumen catheter having one or more non-circular, oval, elliptical or oblong shaped lumens therein and wherein the cross sectional shapes of a plurality of the lumens in the multiple lumen catheters are opposed with respect to each other to minimize the existence of sharp corners or flow restriction areas in the lumen and minimizing the occurrence of septum or catheter wall deflection while maximizing the cross sectional area of the lumens of the catheter.
