Patent ID: 7611831

Claim:
A pathogen-inactivating compound adsorption system for reducing the concentration of a low molecular weight pathogen-inactivating compound in an aqueous biological composition containing cellular elements, wherein the pathogen-inactivating compound adsorption system comprises a housing compatible with the biological composition containing an adsorption medium comprising porous adsorbent particles immobilized within a sintered matrix formed from polymeric particulate material, wherein the diameter of the adsorbent particles ranges from about 100 μm to about 1500 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 batch process, and wherein the system is configured so that the cellular elements in the biological composition treated with the system maintain sufficient biological activity so that said biological composition is suitable for infusion within a human.
