Abstract
Method for in-vivo plasmapheresis utilizing a plurality of elongated hollow microporous filter fibers periodically interrupt diffusion of blood plasma from a patient, and, for a selected time, directing backflush fluid into the fibers at a pressure and interval sufficient to cleanse the fiber pores, after which plasma diffusion is resumed. The backflush fluid, preferably a normal saline solution, may contain an anticoagulant such as heparin, citrate or NO donor in suitable concentration for systemic anti-coagulation or for treating the fiber for thromboresistance.
