ABSTRACT:
A method for removing undesirable material including leukocytes from a biological fluid in an extracorporeal circuit comprises passing a leukocyte containing biological fluid from a patient into a container; passing a portion of biological fluid from the container through a recirculation loop including a filter assembly for removing leukocytes to leukocyte deplete the biological fluid and to pass the portion of leukocyte-depleted biological fluid into the container; passing additional leukocyte containing biological fluid from a patient into the container so that the additional fluid is mixed with leukocyte depleted biological fluid in the container to provide a mixture including leukocyte depleted and non-leukocyte depleted biological fluid; passing the mixture of biological fluid from the container; passing a portion of the mixture to the patient while passing another portion of the mixture through the recirculation loop.
