Abstract :
A new bioartificial liver support system has been developed for the treatment of liver failure. The basis of the system is that the complex functions of the liver are replaced by hepatocytes cultured in a special bioreactor. The system consists of two circuits: the patient circuit and the bioreactor circuit. Fluids in the circuits dialyse against each other through the semipermeable membranes of hollow-fibres in a dialysis cartridge. Toxic molecules from the patient pass across the membrane and are metabolised by hepatocytes cultivated in the bioreactor while hepatocyte-synthesised products pass across the membrane to the patient in the opposite direction.
