ABSTRACT:
An artifical hybrid organ or gland is formed from two serially-interconnected chambers, the first of which comprises an ultrafiltration chamber which forms an ultrafiltrate from the blood stream applied to it and the second of which comprises a cell exchange chamber which, though immunologically isolated by microporous membranes, receives both the bloodstream and the ultrafiltrate and which rapidly exchanges selected constituents with both before they recombine in order to provide a corrected physiological response to constituents in the blood. Additionally, an optional excretory duct may be employed to channel a portion of the treated ultrafiltrate away from the bloodstream.
