Abstract:
1. A system for providing localized treatment of a patient comprising: a) an access device which provides fluid access intermittently and recurrently to a blood vessel of the patient, the access device comprising a cannula having an inflow port, an inflow lumen, an outflow lumen and an outflow port, a first plunger assembly movable through the inflow lumen and which controls access of fluid entering the cannula from the inflow port, the first plunger assembly being movable between an opened position where it allows fluid access into the vessel from the inflow lumen and a closed position where it prevents fluid access into the vessel from the inflow lumen, a second plunger assembly movable through the outflow lumen and which controls access of fluid exiting the cannula from the outflow port, the second plunger assembly being movable between an opened position where it allows fluid access into the outflow lumen from the vessel and a closed position where it prevents fluid access into the outflow lumen from the vessel; b) a movable spatula which separates the inflow lumen and the outflow lumen, wherein a vascular end of the movable spatula is shaped to provide substantially leak proof interaction with a wall of a blood vessel, c) one or more external blood modification systems comprising at least one pump; d) one or more outflow systems providing fluid communication between the blood vessel and the one or more external blood modification systems through the outflow port; e) one or more inflow systems providing fluid communication between the one or more external blood modification systems and the blood vessel through the inflow port.
