ABSTRACT:
An elongated catheter formed with multiple lumens from coextruded or other materials such that the inner surface of the extension members or body portion of the catheter may include a higher durometer than the outer surface of the extension members or body portion of the catheter to reduce septum deflection during normal use, and the likelihood of tearing or sticking of the extension members is reduced and the catheter includes a pair of generally cylindrical lumens and the catheter preferably includes a third lumen which is substantially smaller than the first two lumens and the cross sectional area of the lumens of the catheter are maximized with the septums of the catheter being oriented to maximize the flow of fluids through the catheter.
