LAWRENCE, Mass., Sept. 14 /PRNewswire-FirstCall/ -- NxStage Medical, Inc.

"With nearly two million treatments to date, our Streamline blood tubing set continues to gain traction in the market. As such, we are very pleased that Reliant has selected both Streamline and our MasterGuard needles for integration into their in-center operations," stated Mark S. Florence, Vice President and General Manager of Medisystems Corporation. "This combination of innovative and proven technologies underscores our commitment to bring added clinical and economical value to our customers for the benefit of dialysis patients."

"Reliant is committed to ensuring that our providers have access to innovative and effective health care technology," stated Nola McMullen, Executive Vice President and COO of Reliant Renal Care, Inc. "It is RRC's philosophy that improvements in patient care happen at the chair side; Streamline's ability to reduce alarm occurrences, improve our clearances, and reduce our costs, and the unique safety features of MasterGuard, make the Medisystems' products a good match with our efforts to offer extended modality choices (in-center self care, home hemodialysis and in-center nocturnal programs) to each patient, all the while maintaining safety requirements for patients and caregivers."

Medisystems' latest generation blood tubing set is the Streamline. Streamline features an efficient and airless design intended to improve clinical and economic performance. Streamline is designed to reduce dialysate flow, dialyzer size, treatment time, minimize heparin and waste, and optimize dose delivery, as measured in Kt/V. Streamline also includes Medisystems' patented LockSite® ( )needleless access ports, which eliminate the need for sharp needles or costlier guarded needles to be used with the tubing set during dialysis.
