ABSTRACT:
A single access dialysis needle system comprises a first cannula, a second cannula or sheath, and a barrier arranged on the outer surface of the first cannula. The distal end of the first cannula extends distal to the distal end of the second cannula or outer sheath, and the barrier is positioned between the respective distal ends. When the barrier is inflated or otherwise activated, it prevents or minimizes recirculation.
