ABSTRACT:
The bioartificial reactor has a reactor vessel. A cell culture chamber in the reactor, in particular for liver cells, is divided off from a flow chamber for a nutritive medium and from a flow chamber for plasma and blood by semipermeable walls. At least one flow chamber is formed as a tube that is helically wound in the shape of a screw and that is made of semipermeable material.
