Abstract
Improved devices for blood separations are provided based on the use of hollow fiber membrane arrays in extra-lumenal crossflow filtration. Blood is processed extra-lumenally across an ordered array of microporous hollow fibers to separate cells from plasma. By use of extra-lumenal crossflow filtration with suitably oriented fibers, the separation device is more efficient than existing devices which benefits a patient or donor by reducing extracorporeal volume.
