Abstract: Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.

Abstract: The invention relates to systems and methods for performing dialysis with closed-loop control of sodium and bicarbonate concentrations in the dialysate. The system and methods can use one or more conductivity sensors in a dialysate flow path to determine a water addition rate and a bicarbonate addition rate resulting in a dialysate having desired sodium and bicarbonate concentrations.

Abstract: This disclosure generally relates to at least one reusable module of a sorbent cartridge in a sorbent dialysis system and a method of using the same. One of the drawbacks of a conventional sorbent dialysis system is the high cost. In one aspect of the invention, the sorbent cartridge contains at least one module for optionally recharging sorbent materials in-line with an optional bypass and conduits for the sorbent cartridge. The sorbent cartridge can have two or more modules that are connected to one another through connectors. The modules can be reusable and the sorbent materials contained in the modules can be recharged.

Abstract: A sorbent cartridge comprising one or more detachable modules. The sorbent cartridge can have one or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein recharged. The sorbent cartridge can include a module containing an anion exchange resin, such as zirconium oxide, downstream of zirconium phosphate in the sorbent cartridge to recapture phosphate anions that leach out of the zirconium phosphate.

Abstract: Methods and related apparatuses for sorbent recharging are provided. The methods and related apparatuses for recharging can recharge a specific rechargeable layer of a sorbent material such as zirconium oxide and/or zirconium phosphate in a sorbent cartridge. The methods and apparatuses include passing solutions containing aqueous basic solutions through the zirconium oxide. The apparatus allows for recharging the zirconium oxide, and also for recharging zirconium phosphate, wherein the sorbent materials are contained in reusable sorbent modules.
