Abstract: A blood treatment system and method controlling same are provided. The system comprises a blood pump for urging blood from an arterial or venous interface through a blood flow path; a dialyser in fluid communication with said blood flow path for ultrafiltering the blood to remove fluid therefrom; a fluid removal pump in fluid communication with said dialyser for urging ultrafiltered fluid away from said dialyser; a controller in signal communication with said blood pump; and a reversing valve for selectively reversing direction of blood flow in at least a portion of the blood flow path under signal control of said controller. The blood pump is selectively activatable under signal control of the controller.

Abstract: A system and method for controlling a renal therapy device is provided. The system comprises a controller for performing a method comprising: receiving a first power level of a first battery to determine if the first power level of the first battery is above a threshold value and receiving a second power level of a second battery to determine if the second power level of the second battery is above the threshold value. When the first power level is above the threshold value, the controller causes the renal therapy device to be powered by the first battery. When the first power level is below the threshold value, and the second power level is above the threshold value, the controller causes the renal therapy device to be powered by the second battery. The first battery is electrically isolated from the second battery.

Abstract: A biocompatible and hemocompatible material and filter which is suitable for blood filtration applications. Biocompatibility and hemocompatibility is achieved through a modification of an existing ceramic substrate, in which a pyrolytic carbon layer is coated onto the filter.
