Microemboli-free blood detoxification utilizing plasma filtration.

Abstract

Guest Editor's Introduction: This paper was originally presented at the 22nd ASAIO Congress in April 1976 and printed in Volume 22, Trans Am Soc Artif Int Organs, 1976, pages 637–644. It is reprinted with permission in Therapeutic Apheresis Volume 4, Issue 1, as a millennium project of the International Society for Apheresis. This is the first paper describing flat sheet microporous hydrophilic membranes for plasmaseparation. Sixteen membranes of different pore structures and different base polymers were subjected for evaluation. A celanese polypropylene membrane of pore diameters between 0.04–0.2 μ, and a nuclepore polycarbonate membrane of pore diameter between 0.2–0.4 μ were satisfactory as plasma separator flat sheet membranes.
