1. A method for acquiring access to the central venous system of a patient at a target location near an occlusion of a jugular vein, comprising the steps of:

  • introducing a guide catheter into a blood vessel at a location remote from said occlusion;

    advancing a needle wire having a sharp end transvascularly through the guide catheter until its sharp end is adjacent the occlusion;

    rotationally adjusting said needle wire until its sharp end is aimed toward the desired skin exit location;

    advancing the needle wire to puncture the blood vessel from the inside out at a vascular exit site adjacent the occlusion, thereby establishing a tissue track;

    further advancing the needle wire along said tissue track thereby extending said tissue track to puncture the skin from the inside out near said vascular exit site.
