Allient™ hemodialysis machine: Sorbent‐based, single‐needle, UF‐controlled dialysis reborn.

By the year 2000, there was rising interest in home hemodialysis in the United States. HemoCleanse decided to resurrect the BioLogic‐HD machine, using updated components. A spin‐off company Renal Solutions (RSI) created the Allient™, with sorbent regeneration of dialysate, hollow fiber dialyzer, pressure‐controlled blood flow rate, controlled filtration, and single‐ or dual‐needle access. RSI merged with Sorb Technology and the Allient™ was built, tested, and FDA‐approved to market. In 2007 Fresenius Medical Corporation (FMC) bought RSI. FMC began an extensive re‐design of the machine to fit the needs of both in‐center and home dialysis. The redesigned machine never was marketed. [ABSTRACT FROM AUTHOR]
