ABSTRACT:
The bio-artifical pancreas comprises islands of Langerhans contained in a volume defined by two approximately parallel ultrafiltration membranes, able to be formed by two successive portions of the same flat membrane or the same hollow fiber. The surfaces of the membrane opposite the volume occupied by the islands are successively swept by the same blood stream over a length greater by at least one order of size than the distance separating the membranes.
