1. A vascular access system for facilitating repeated access to a blood vessel, the apparatus comprising:

  • (a) a graft vessel means for providing a fluid conduit, the graft vessel means having an anastomosis end and an opposite port end, the graft vessel means being adapted for anastomosis at its anastomosis end with a blood vessel;

    (b) means for selectively occluding an opening in a blood vessel at the anastomosis end of the graft vessel means, said occluding means being positioned at the anastomosis end of the graft vessel means, said occluding means being adapted for distension and contraction at the anastomosis end of the graft vessel means to enable the occluding means to block fluid communication between the graft vessel means and a blood vessel when expanded in a distended position and to permit fluid communication between the graft vessel means and the blood vessel when contracted to a contracted position; and

    (c) means for selectively providing access to the occluding means, the means for selectively providing access being attached in a leak proof manner to the occluding means to provide fluid communication, the means for selectively providing access being configured to remain within a patient'"'"'s body after anastomosis of the graft vessel means to the blood vessel while being accessible from outside of the patient'"'"'s body to deliver and withdraw fluids and cause selective distention and contraction of the occluding means.
