Abstract: Systems and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system for performing kidney replacement therapy has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. The dialysis circuit and an extracorporeal circuit for circulating blood are in fluid communication through the dialysis membrane. The flux of fluid moving between the extracorporeal circuit and the dialysis circuit is modified by the rate at which the control pump is operating such that a rate of ultrafiltration and convective clearance can be controlled. The system provides for the monitoring of an inlet and outlet conductivity of the sorbent cartridge to provide a facility to quantify or monitor the removal of urea by the sorbent cartridge.

Abstract: The invention relates to infusate containers and related systems and methods for housing infusates that can be added to a fluid flow path for use during dialysis. The infusate containers can include a filter partitioning the containers into a first and second compartment, a draw tube for drawing up fluid from a bottom portion, a cap, a fluid connector for delivery and withdrawal of fluid from the two compartments, and a fluid connector for connection to a dialysis system.

Abstract: Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two 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 can be recharged.

Abstract: A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.

Abstract: A sensing and storage system for fluid balance during dialysis is provided. The sensing and storage system has flow sensors on either side of a dialyzer in a controlled volume dialysate flow path. The sensors are positioned so that no fluid can be added to or removed from the dialysate flow path between the sensors except for that which is added or removed by action of a control pump. The sensing and storage system can have a fluid removal line for the removal of fluid from the dialysate flow loop.
