A tunneler (100) for a dual lumen tip catheter, comprises an elongated body (102) extending from a distal tissue-penetrating end to (112) a proximal, catheter-coupling end (106) , the catheter coupling end including a catheter tip receiving portion including a cutout (110) sized and shaped to receive a dual lumen tip of a catheter to be coupled thereto and a proximally extending lumen-mating protrusion (108) oriented so that, when inserted into a lumen of the catheter, the dual lumen tip of the catheter is received in the cutout in an orientation relative to an elongated body of the catheter substantially the same as when the dual lumen tip and the elongated body of the catheter are in an unstressed state.
