1. A method for providing access to a central venous system of a patient comprising:
applying a radiopaque target having a radiopaque area and a radiolucent area to the skin of the patient so that the radiolucent area defines an exit point on the skin of the patient;
introducing a catheter into the patient in an area remote from the exit point, wherein the catheter has a departure angle guide tube configured to extend out a side aperture of a distal tip of the catheter in a departure angle plane, to set a departure angle, and a needle wire configured to extend through the departure angle guide tube;
advancing the catheter to position said distal tip in a desired tip location in the central venous system;
viewing the catheter and said distal tip under fluoroscopy through the radiolucent area of the radiopaque target;
rotating the catheter so that the side aperture and therefore the departure angle plane is aligned with the radiolucent area of the radiopaque target;
adjusting the departure angle guide tube so that the departure angle is aimed at the radiolucent area of the radiopaque target; and
advancing the needle wire through the departure angle guide tube, through the skin of the patient, and through the radiolucent area of the radiopaque target thereby providing an exteriorized needle wire at said exit point.
