A mass transfer device having a fluid permeable core wound with many stands of a hollow fiber. A bulk fluid enters the interior of the core, passes through the side wall of the core, and along the outer surfaces of the hollow fibers. A baffle positioned in the center of the core so that the bulk fluid passes outwardly upstream of the baffle and inwardly through the core along the downstream of the block.

Radial dispersion mass transfer device having a semi-permeable tubular hollow fiber membrane wound around a porous core

A bi-component microporous hollow fiber membrane structure is provided for in vivo propagation of cells and use in testing of the effect of medical treatments on cells within the structure. The structure has an inner structure fabricated from a first bio-compatible polymer and an outer structure fabricated from a different polymer that has a lower tendency for cell adhesion than the inner structure polymer. In this way, the inner structure can be selected to optimize cell propagation and the outer structure can be fabricated from a polymer which optimizes the removal of the bi-component structure from its implanted location. The inner and outer structures may have a pore size between 10 and 1000 Angstroms and 100 and 2000 Angstroms, respectively, and be formed from polysulfone or polyether sulfone and polyvinyledene difuoride, respectively. The membrane structure can form macrocapsules containing media and living cells for implanting.
