Summary: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. La présente invention concerne un procédé d'élimination de cytokines et/ou de pathogènes du sang ou du sérum sanguin (sang) par la mise en contact du sang avec un substrat solide, essentiellement non microporeux qui a été traité en surface par de l'héparine, de l'héparan sulfate et/ou d'autres molécules ou groupes chimiques (le milieu adsorbant ou milieu) ayant une affinité de liaison pour la cytokine ou le ou les pathogènes à éliminer (les adsorbats), la dimension des canaux interstitiels au sein dudit milieu étant équilibrée avec la quantité d'aire de surface de milieu et la concentration en surface de sites de liaison sur le milieu, afin de fournir une capacité d'adsorption adéquate tout en permettant également des débits relativement élevés de sang à travers le milieu adsorbant.
