About the NxStage System One

The NxStage System One is the first and only truly portable hemodialysis system cleared for home use by the U.S. Food & Drug Administration (FDA). The System One also has a CE mark and has been cleared by Health Canada. Its simplicity and revolutionary size (just over a foot tall) provide convenient use in patients' homes and give patients the freedom to travel with their therapy. Unlike conventional hemodialysis systems, the System One requires no special infrastructure to operate. Under the guidance of their physician, patients can use the NxStage System One, with their trained partners, where, how and when it best meets their needs, at home or on the road.
