  • Publication number: 20100297078
    Abstract: A method of producing a hydroxyalkyl starch (HAS) derivative, comprising a) reacting optionally oxidized hydroxyalkyl starch with a compound (D) comprising at least two functional groups —O—NH2 or a salt thereof, and b) reacting the hydroxyalkyl starch derivative obtained in step a) with a compound (L) comprising at least two functional groups W1 and W2 independently selected from the group consisting of an aldehyde group, a suitably protected aldehyde group, a keto group, and a suitably protected keto group.

  • Patent number: 7838306
    Abstract: An adsorbent for whole blood in the form of essentially spherical non-aggregated particles. The adsorbent comprises a porous carrier material having an average pore size of ?1.5 ?m, whereby a maximum of 50% of the pore volume may be in pores having a pore size of >1.5 ?m, whereby the outer surfaces of the porous carrier material have at least one surface modification M1 so that the outer surface essentially does not interact with blood cells, and the inner surfaces of the porous carrier material, e.g., the surfaces of the pores of the porous carrier material, have at least one surface modification M2 which interacts with substances present in blood.

  • Publication number: 20050036979
    Abstract: This invention relates to an adsorbent for lowering the concentration of fibrinogen and/or fibrin in the blood or blood plasma, encompassing an organic matrix with synthetic side chains covalently bound to the matrix and exhibiting terminal vicinal hydroxy groups formed by the hydrolysis of terminal epoxy groups, which synthetic side chains are free of peptides and of any groups of aromatics. The invention further relates to a method for preparing the adsorbent, and to the use of the adsorbent for producing an adsorber serving to lower the concentration of fibrinogen and/or fibrin in the blood or blood plasma.
