Abstract: A method to remove virulence factors from infected blood by passing the blood through a surface cartridge with immobilized carbohydrates, such as heparin, wherein the virulence factors are toxins released from pathogens such as B. anthracis, S. aureus, and P. aeruginosa.
Abstract: The present invention is directed to a method for removing cytokines and/or pathogens from blood or blood serum (blood) by contacting the blood with a solid, essentially non micro-porous substrate which has been surface treated with heparin, heparan sulfate and/or other molecules or chemical groups (the adsorbent media or media) having a binding affinity for the cytokine or pathogen(s) to be removed (the adsorbates), and wherein the size of the interstitial channels within said media is balanced with the amount of media surface area and the surface concentration of binding sites on the media in order to provide adequate adsorptive capacity while also allowing relatively high flow rates of blood through the adsorbent media.

Abstract: The present invention relates to a device for extracorporeal removal of harmful agents from blood or blood components, comprising full length heparin immobilized on a solid substrate by covalent end point attachment. The present invention also relates to a method for extracorporeal removal of a harmful agent from mammalian blood or blood components. The present invention further relates to a process for covalent end point attachment of full length heparin to a solid substrate.
