1. A tunneling system comprising:
a catheter having a proximal end, a distal end, first and second longitudinal lumens separated by a septum, and at least one hole extending through the septum from the first longitudinal lumen to the second longitudinal lumen and providing passage between the first and second lumens, the at least one hole being spaced from the proximal end of the catheter; and an elongate tunneling member defining a longitudinal axis along at least a portion of a longitudinal length thereof, the elongate tunneling member having a first end and a second end, the second end including a coupling segment integrally formed therewith, the coupling segment adapted for at least partial reception within at least one of the longitudinal lumens of the catheter, and wherein the coupling segment includes at least one protrusion adapted to be received within the at least one hole extending through the septum to secure the catheter to the tunneling member. |
