ABSTRACT:
A support material is fed through mating elements which emboss transverse score lines thereon to form an accordion fold in the material. A single thickness of the folded support material is then interleaved with a permeable membrane and sealed in a housing to form a compact inexpensive flat plate dialyzer. Longitudinal channels are formed in the support material which materially improve distribution of fluids within the dialyzer.
