Chronic Cartridges

The NxStage cartridge (with PUREMA H membrane) is used with NxStage System One and provides patient flexibility for more frequent, nocturnal, or intermittent renal replacement therapy at home.

NxStage Chronic Cartridges offer:

  • Easy set-up
  • Flexible therapy options including more frequent and nocturnal
  • Effective removal of small and middle molecular toxins with simultaneous retention of valuable proteins and achievement of high clearances due to:
    • Even dialysate distribution1
    • Excellent biocompatibility1

NxStage offers a selection of cartridge configurations used for hemodialysis treatments performed in the home, during the day, or overnight while the patient sleeps.
