Disclosed are preferred devices and methods which provide extracorporeal treatment of blood or other fluids for effective plasmafiltration or hemofiltration alone or in combination with dialysis. Preferred devices combine plasmafiltration and dialysis devices, and are designed to circulate separate sorbent suspensions through the respective devices and minimize clogging in sorbent circulation loops, including the provision of a shaker or vibrator device operable to vibrate the suspension used in the plasmafiltration device.

[ What is claimed is:] [18.] A filtration process for removing blood toxins, comprising:passing a fluid containing protein bound and/or middle molecular weight blood toxins through the interior of a hollow fiber membrane;during said passage of fluid, providing a sorbent suspension exterior of said hollow fiber membrane; andduring said passage of fluid, periodically creating pressure differentials across the hollow fiber membrane with a pump so as to cause bi-directional flow in which the fluid or a fraction thereof alternately exits and re-enters the interior of the hollow fiber membrane, wherein said exiting fluid or fraction contains the protein bound and/or middle molecular weight toxins which contact said sorbent suspension so as to effectuate removal of said toxins from said fluid.
