ABSTRACT:
A method for carrying out therapeutic apheresis comprises separating plasma from whole blood in-vivo and removing selected disease-related components from the separated plasma. Apparatus for carrying out therapeutic apheresis includes a filter device for being implanted in a blood vessel for carrying out in-vivo plasma separation having one or more elongated hollow tubes and a plurality of elongated hollow microporous fibers capable of separating plasma from whole blood at pressure and blood flow within a patient's vein, a multiple lumen catheter secured to the proximal end of the filter device having one or more lumens in fluid communication with the interior of said one or more hollow tubes and a plasma return lumen, and therapeutic apheresis apparatus for removing and/or separating selected disease-related components from the separated plasma and means for directing plasma between said catheter and the selective component removal apparatus.
