Patent ID: 6951713

Claim:
A pathogen-inactivating compound adsorption system for reducing the concentration of a low molecular weight pathogen-inactivating compound in a biological composition, wherein the pathogen-inactivating compound adsorption system comprises a housing compatible with the biological composition and containing an adsorption medium comprising adsorbent particles having a network pore structure immobilized within a sintered matrix formed from polymeric particulate material, wherein the diameter of the adsorbent particles ranges from about 1 μm to about 200 μm, wherein the adsorbent particles have an affinity for said pathogen-inactivating compound, wherein the system is configured to remove said pathogen-inactivating compound from said biological composition in a flow process, wherein the system is configured so that the biological composition treated with the system maintains sufficient biological activity so that said biological composition is suitable for infusion within a human.
