Patent number: 8070706Abstract: 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.Type: GrantFiled: January 13, 2009Date of Patent: December 6, 2011Assignee: Transvivo, Inc.Inventors: Reynolds G. Gorsuch, Tommy Gene Cooper, Harold H. Handley, Jr., Harold W. Peters

Patent number: 7585412Abstract: A plasmapheresis and/or ultrafiltration membrane comprises elongated hollow fibers each fiber having an interior lumen extending along the fiber length, the fiber wall having a plurality of zones between the inner and outer wall surfaces, each of the zones having a mass density different than the mass density of an adjacent zone. The fiber wall is characterized by having a lower mass density zone at the inner wall surface and a higher mass density zone at the outer wall surface. The fiber is further characterized by having an average elongation breaking force strength of at least about 0.2 lbs. and an average elongation of at least about 45%.Type: GrantFiled: April 14, 2006Date of Patent: September 8, 2009Assignee: Transvivo, Inc.Inventors: Reynolds G. Gorsuch, Henry Grage, Harold H. Handley, Jr., Harold W. Peters, Jacob C. Kearns
