A catheter for delivering and withdrawing blood from a patient's body, the catheter comprising: a catheter body having a distal portion, a return lumen extending from a proximal portion of the catheter body to the distal portion to allow blood passage therethrough, and at least three longitudinally extending intake lumens independent of the return lumen, the intake lumens radially displaced with respect to the return lumen； at least three intake extension tubes each communicating with one of the at least three intake lumens to provide fluid communication with the respective intake lumen； and an outer sleeve retaining the at least three extension tubes, the outer sleeve dimensioned to receive a clamping member such that the clamping member seals off fluid flow in all intake extension tubes.
