Abstract: A sorbent cartridge that has at least one sensor located within the sorbent cartridge.

Abstract: The invention relates to devices, systems, and methods for recharging zirconium phosphate. The devices, system, and methods use a patient pre-dialysis BUN level to set one or more recharge parameters for recharging the zirconium phosphate. The devices, systems, and methods allow for precision recharging of the zirconium phosphate based on the patient pre-dialysis BUN level.

Abstract: A device includes (i) a housing defining an interior, wherein the interior has a blood compartment, a plasma compartment, and a fluid compartment; (ii) a first filter disposed in the interior of the housing, and (iii) a second filter disposed in the interior of the housing. The first filter separates at least a portion of the blood compartment from at least a portion of the plasma compartment. The first filter is configured to allow plasma components, but not cell components, of blood to pass through the first filter from the blood compartment to the plasma compartment. The second filter separates at least a portion of the plasma compartment from at least a portion of the fluid compartment. The second filter is configured to allow fluid and small molecules, but not larger components, to pass through the second filter from the plasma compartment to the fluid compartment. The device may include a sorbent in the plasma compartment to remove or reduce the concentration of selected components of the plasma.

Abstract: Systems and methods for managing the potassium concentration of a dialysate fluid during hemodialysis therapy using cation exchange materials that do not release sodium ions.
