Claim:
1. A tunneling device for creating a pathway in subcutaneous tissue of a person's body, said tunneling device comprising: a semi-rigid member having a length along a longitudinal axis, the length extending between two ends, each of the ends engaged to a collar, each of said collars being hollow along its length and engaged to the semi-rigid member by opposing surfaces, the opposing surfaces spaced from one another along the longitudinal axis to form a longitudinal gap between the opposing surfaces such that each of the collars are secured to the semi-rigid member, and while secured, the longitudinal gap provides for each of said collars to remain independently rotatable as to the length of the semi-rigid member and each other, the semi-rigid member having a tapered dilating surface on the length of the semi-rigid member adjacent each said end, and each collar including a tip removably connected to each collar opposite the semi-rigid member and defining an insertion surface, the insertion surface separate from the respective tapered dilating surface, wherein the insertion surface is configured to facilitate insertion of the ends into the subcutaneous tissue of the person's body, wherein, once connected, the tip and collar rotate as one relative to the semi-rigid member; and an interchangeable handle connectable to each of said ends.
