Abstract
An apparatus for the continuous in vivo separation of plasma from other blood components comprising a bundle of microporous hollow fibers inserted into the vena cava. The fibers are sized to permit diffusion of plasma through the fiber pores but not cellular or other larger blood components. The fibers are in fluid communication with a dual lumen catheter which removes plasma from the hollow fibers to a treatment system and returns treated plasma to the bloodstream. The apparatus can be incorporated into an ambulatory plasma separator system for providing continuous plasma treatment while the user is mobile.
