Removal selectivity of Prometheus: A new extracorporeal liver support device

Figure 1 The albumin fraction of the patient’s blood is filtered through an albumin-permeable membrane (AlbuFlow^®) into a secondary circuit. There, the separated albumin fraction is purified by direct adsorption of albumin-bound toxins using one or two adsorbers (Prometh01^® and Prometh02^®). The plasma is then pumped back into the primary circuit where a conventional high-flux dialysis (FX 50) is performed.
