Abstract:
A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.

Claim (Index 55):
A system comprising a circuit of catheters for delivering a high concentration of a small molecule chemotherapeutic agent to a subject in need of treatment while minimizing systemic exposure to the small molecule chemotherapeutic agent, comprising:\n a catheter inserted percutaneously into the inferior vena cava of a patient in need of treatment, the catheter comprising a hemo-compatible tube having a cranial end and a caudal end, the hemo-compatible tube defining a main lumen for outflowing blood, two balloons, fixedly spaced apart about the hemo-compatible tube and bonded thereto for inflation thereabout, one being contiguous to the cranial end, and the balloons, when inflated, having a size sufficient to block the flow of blood in a vein or artery into which the first catheter is designed to be inserted; fenestrations in the hemo-compatible tube between the balloons to the main lumen; second and third lumina within the hemo-compatible tube, the second lumen connecting to one of the balloons and the third lumen connecting to the other of the balloons, or other expandable devices, for effecting inflation or deflation of the balloons, the cranial end of the hemo-compatible tube effectively blocking inflow of blood, and a filter apparatus comprising a housing having an inlet and an outlet, an extraction media comprising hemocompatible polymer coated carbon cores contained within the housing, wherein the polymer coated carbon cores have a pore volume of about 1.68 cc/g to about 2.17 cc/g, wherein the filter apparatus is capable of being connected via a connector to the first catheter and a flow machine for pumping the blood from the subject through the filter apparatus, and a sheath or return catheter for returning blood removed from the patient back to the patient after filtration.
