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.
