A dialysis catheter comprising a first portion having a first dianeter, an elongated distal portion having a second diameter smaller than the first diameter, and a transition region between the first portion and distal portion. A first longitudinally extending central lumen configured to deliver blood terminates in an opening in the distal portion. At least two independent longitudinally extending lumens are positioned radially of the first lumen, configured to withdraw blood from a patient, and terminate in a longitudinally directed opening in the transition portion.
