Abstract
An adsorbent for reducing the concentration of fibrinogen and/or fibrin in blood or blood plasma comprises a matrix and synthetic lateral chains that are covalently bonded to the matrix. The lateral synthetic chains are comprised of at least two amino groups in which the N atoms are at least 2.6 Å apart within at least one lateral synthetic chain. The matrix exhibits porous, unaggregated, spherical particles in a range of particle sizes from 50 to 250 &mgr;m, which possess an exclusionary threshold of at least 10 Daltons, and they exhibit no peptides or aromatic groups of any kind. The at least two amino groups are preferably separated from one another by 4 to 6 carbon atoms. An adsorber for the purpose of reducing the concentration of fibrinogen and/or fibrin in blood or blood plasma may be produced from the adsorbent.
