  • Publication number: 20240050907
    Abstract: The present disclosure relates to semipermeable membranes which are suitable for blood purification, e.g. by hemodialysis, which have an increased ability to remove larger molecules while at the same time effectively retaining albumin. The membranes are characterized by a molecular retention onset (MWRO) of between 9.0 kD and 14.5 kD and a molecular weight cut-off (MWCO) of between 55 kD and 130 kD as determined by dextran sieving curves and can be prepared by industrially feasible processes excluding a treatment with salt before drying. The invention therefore also relates to a process for the production of the membranes and to their use in medical applications.

  • Patent number: 11517855
    Abstract: The present disclosure relates to an artificial, extracorporeal system for supporting the function of the liver of a patient suffering from liver failure, which is characterized in that it comprises a first high-flux or high cut-off hollow fiber membrane dialyzer which is perfused on the lumen side with the patient's blood and wherein a buffered aqueous solution comprising human serum albumin is passed in a continuous flow through the filtrate space of said first dialyzer, a second hollow fiber membrane dialyzer which removes water-soluble substances from the dialysate of said first dialyzer, and a third, integrated hollow fiber membrane dialyzer which is perfused with the retentate of second hemodialyzer and which allows the passage of certain amounts of albumin over the membrane wall into the filtrate space which is populated with adsorbent material. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.
