    Abstract: Blood separation systems and methods introduce blood into an annular separation channel between a low-G wall and a high-G wall while rotating the separation channel about an axis, for separation of the blood into blood components. The annular separation channel has an annular boundary wall. The systems and methods direct a first blood component into a constricted channel along the low-G wall. The systems and methods remove the first blood component through a first path that communicates with the separation channel through an opening that adjoins the constricted channel adjacent the low-G wall. The systems and methods direct a second blood component along a surface that extends generally in an axial direction along the high-G wall toward the annular boundary wall. The systems and methods collect the second blood component through a second path that communicates with the separation channel through an opening that adjoins the surface adjacent the high-G wall axially spaced from the annular boundary wall.

    Abstract: Systems and methods rotate a chamber (14), in which whole blood is centrifugally separated into an interface between the packed red blood cells and the plasma constituent. The interface carries platelets and mononuclear cells. The systems and methods include an interface control unit which is operative in a first state to enable removal of platelet-poor plasma (PPP) in a first container for use as a diluting liquid, and in a second state, to retain mononuclear cells (MNC) in the chamber (14), while removing platelet-rich plasma (PRP) from the chamber (14), bypassing the platelet-poor collection container, thereby maintaining its platelet-poor character, and in a third state to enable the removal of mononuclear cells (MNC) from the chamber (14) in a path (T13) that leads to a second container, where the mononuclear cells are collected.
