Porous composite hemostatic sponge consisting essentially of i) a matrix of a biomaterial and ii) a simple hydrophilic polymer component that includes electrophilic reactive groups, said hydrophilic polymer component being a hydrophilic crosslinker, being i) and ii) associated with each other so that the reactivity of the polymer component is preserved, where the term "associated" means - that said polymer component is applied on a surface of said biomaterial matrix, or - that said matrix is impregnated with said polymeric material, or - both. |
