ABSTRACT:
A membrane diffusion device, such as a membrane oxygenator, is disclosed which comprises a stack of flat membrane wall pairs and flat membrane supports in alternating, interleaving relation. The casing includes a pair of opposed sidewalls that are substantially parallel to flat sides of the stack, and a pair of substantially vertical crimps are formed on each of the sidewalls to provide external compression on the end portions of the stack.
