NxStage Medical Inc. subsidiary Medisystems Corp. inked a new, three-year supply deal with Reliant Renal Care Inc. to provide its blood tubing sets and safety needles to Reliant’s network of 12 dialysis centers.

The Lawrence, Mass.-based renal products maker said the deal will see Medisystems supply Streamline blood tubing sets and MasterGuard safety needles to Reliant centers in Alabama, Michigan, Texas and Colorado.

It’s only the latest supply deal for NxStage, which in May signed a $40 million deal with Asahi Kasei Kuraray Medical to private-label its dialyzer under the Asahi name in return for debt financing and the supply of Asahi’s line of high-performance polysulfone hollow-fiber membranes.

Days later the company announced a re-up of its deal with B. Braun Medical to supply the Streamline tubing sets. And in mid-June, Medisystems agreed to provide Gambro Renal Products Inc. with ReadySet and Streamline tubing sets.

In late July, Medisystems struck again, this time extending a deal to provide Fenwal with the MasterGuard needle sets.

NxStage posted a $12.5 million loss on $36.4 million in sales during the second quarter, compared to a $12.5 million loss on $31.6 million for the same period last year.
