1. A catheter system for directing the flow of blood through the vasculature of a patient, comprising:

  • a catheter comprising a catheter body having a proximal end, a first distal end, and a second distal end, said first distal end extending distally farther from the proximal end than the second distal end;

    a first lumen extending between said first distal end and said proximal end;

    a second lumen extending between said second distal end and said proximal end; and

    a redirecting tip having a surface positioned at the distal end of and within one of the first and the second lumens; and

    a pump in fluid communication with the catheter and configured with withdraw blood from one of said lumens and to deliver blood to the other of said lumens;

    wherein blood delivered into one of said lumens of said catheter body impacts said surface and is redirected into the vasculature in a direction generally opposite of the direction of flow in the lumen.
