Claim 13:
14. A catheter system, comprising:
a hemodialysis catheter including a hub coupled to a catheter tube having at least one lumen; and
a refreshing stylet configured to fit within the at least one lumen of the hemodialysis catheter including an elongated hollow body including:
a proximal portion coupled to a needleless connector;
a distal portion ending in a distal tip;
an interior surface;
an exterior surface coated with a sustained-release formulation including one or more anti-thrombotic agents configured to contact a luminal surface of the hemodialysis catheter and prevent thrombus formation on the luminal surface of the hemodialysis catheter, wherein a terminal portion of the distal portion is coated with the sustained-release formulation such that when the refreshing stylet is inserted in the hemodialysis catheter it refreshes a commensurate portion of the at least one lumen of the hemodialysis catheter; and
a side hole through the elongated hollow body connecting the interior surface with the exterior surface, the side hole configured to provide a locking solution to the at least one lumen of the hemodialysis catheter for locking the hemodialysis catheter between uses.
