Abstract
Methods and apparatus for practical extracorporeal separation of fluorochemicals from clinically fluorochemical-containing whole blood of a patient. The methods incorporate centrifugal apheresis devices, preferably with low extracorporeal volumes, that provide a means for continuously removing separated fluorochemical-enriched fractions from the centrifuge during processing and return of whole blood-enriched fractions to the patient.
