    Abstract: Systems and methods convey the blood through a gap defined between an inner surface that is located about an axis and an outer surface that is concentric with the inner surface. At least one of the inner and outer surfaces carries a membrane that consists essentially of either a hemofiltration membrane or a hemodialysis membrane. The systems and methods cause relative movement between the inner and outer surfaces about the axis at a selected surface velocity, taking into account the size of the gap. The relative movement of the two surfaces creates movement of the blood within the gap, which creates vortical flow conditions that induce transport of cellular blood components from the membrane while plasma water and waste material are transported to the membrane for transport across the membrane. Shear-enhanced transport of waste materials and blood plasma water results.

    Abstract: A blood separation system (10) is described. The system comprises a device (14, 18) which, in use, operates to separate whole blood into red blood cells and plasma, a whole blood inlet line (290) for conveying a flow of whole blood into the device, a plasma collection line (292) for conveying a flow of plasma from the device, and a red blood cell collection line (294) for conveying a flow of red blood cells from the device. A first sensing assembly (334) including a first sensor in the plasma collection line is provided which in use operates to detect a characteristic of plasma in the flow of plasma and to generate a first output. A second sensing assembly (336) including a second sensor in the red blood cell collection line is provided which in use operates to detect a characteristic of red blood cells in the flow of red blood cells and to generate a second output. A controller (16) operates to control flows in the plasma collection line and the red blood cell collection line based upon the first and second outputs.

    Abstract: Automated systems and method for processing blood and other fluids are disclosed. The systems and methods utilize a disposable fluid circuit mounted on a re-usable hardware component or module. The system withdraws blood from a donor or patient, separates the blood into two or more components and further processes or treats the separated component.
