    Abstract: Blood processing systems and methods establish on line communication between a container and a source of blood containing leukocytes and platelets, such as a human donor. The systems and methods create a centrifugal field between the source of blood and the container that separates from the blood an unfinished suspension of platelets having a first physiologic characteristic different than the desired physiologic characteristic. The systems and methods pump the unfinished platelet suspension outside the centrifugal field through a finishing device. The finishing device changes the first physiologic characteristic to the desired physiological characteristic, thereby creating the finished platelet suspension. The systems and methods convey the finished platelet suspension from the finishing device directly into the container. The systems and methods function without interrupting the on line communication between the container and the source of blood.

    Abstract: Blood separation systems and methods employ a rotating chamber. The chamber includes an inlet region where whole blood enters for centrifugal separation into packed red blood cells, a plasma constituent, and an interface carrying mononuclear cells between the packed red blood cells and the plasma constituent. The packed red blood cells in the chamber have a hematocrit value HPRBC. A controller operates in a first mode to convey whole blood into the inlet region while removing packed red blood cells and the plasma constituent from the chamber and while maintaining the interface within the chamber. The controller also operates in the first mode to maintain a set HPRBC by conveying packed red blood cells into the inlet region.
