"HDF represents an alternative treatment option for chronic renal failure, and I am excited that patients in the United States will now have the opportunity to be treated with this important therapy," said Leonard Stern, M.D., Medical Director at Columbia University Dialysis Center, and Associate Clinical Professor of Medicine, Columbia University, College of Physician and Surgeons.

"Nephros can now offer the only on-line HDF therapy available in the U.S.," said John C. Houghton, President & CEO of Nephros, Inc.  "Nephros will first pursue a limited launch of its HDF system before expanding into the broader market.  In parallel, Nephros will evaluate opportunities to leverage the resources of a strategic partner to most effectively address the market."
