Adsorbent for reducing the concentration of fibrinogen and/or fibrin, method of producing an adsorber from the adsorbent, and an adsorber with the adsorbent

An adsorbent for reducing the concentration of at least one of fibrinogen and fibrin in blood or blood plasma, comprising:

• a matrix;
• and
• at least one synthetic lateral chain covalently bonded to the matrix and containing at least two amino groups whose nitrogen atoms are at least 2.6 Å removed from one another within the at least one synthetic lateral chain, wherein the at least one synthetic lateral chain is peptide-free and contains no aromatic groups, wherein the at least one synthetic lateral chain is 2-amino-5-diethyl aminopentane.

A method of producing an adsorber for the purpose of reducing the concentration of at least one of fibrinogen and fibrin in blood or blood plasma, said method comprising:

• adding an adsorbent to a housing to form an adsorber, wherein the adsorbent comprises:
• a matrix;
• and at least one synthetic lateral chain covalently bonded to the matrix and containing at least two amino groups whose nitrogen atoms are at least 2.6 Å removed from one another within the at least one synthetic lateral chain, wherein the at least two amino groups are separated from each other by between one and four atoms, and wherein the at least one synthetic lateral chain is peptide-free and contains no aromatic groups.
