This invention uses “targeted apheresis” to treat rheumatoid arthritis patients. “Targeted Apheresis” is a process whereby the RF and immune complexes responsible for causing the disease symptoms are selectively removed from the blood by passing the blood through a cartridge containing immobilized IgG. The RF and immune complexes are bound out and the cleaned blood is returned to the patient Removal of circulating RF and immune complexes will ameliorate the symptoms of rheumatoid arthritis.
