Barry is a tremendous and timely addition to the NxStage Board, bringing demonstrated and recognized leadership in the healthcare public policy arena, said Jeffrey Burbank, Chief Executive Officer, NxStage Medical, Inc. He will provide NxStage and our Board with invaluable guidance as we advance our long term growth strategy and continue to mature reimbursement for more frequent home hemodialysis with the System One&#153.

I’ve known NxStage for many years and have a great deal of respect for their discipline in developing the clinical and economic fact base to support home, more frequent hemodialysis with the System One, said Dr. Straube. I truly believe that home, more frequent hemodialysis can play a significant part in achieving Medicare’s goals for patient-centered care that leads to better health outcomes and associated lower costs. I’m excited to bring a unique perspective to the Board and look forward to working with the Board, Jeff, and the management team to advance NxStage’s vision.

Its simplicity and compact size are intended to allow easy use in patients’ homes and give patients the opportunity to travel with their therapy.
