| abstract |
The present invention provides a hemostatic porous composite sponge, comprising: i) a matrix of a biomaterial, and ii) a hydrophilic polymer component comprising reactive groups, wherein i) and ii) are associated with each other so that the reactivity of the polymer component is retained, where associated means that said polymer component is placed as a coating on a surface of said matrix of a biomaterial, or said matrix is impregnated with said polymeric material, or both. |
