Claims30
A hemostatic composite sponge comprising a porous sponge of a matrix of a biomaterial and a material enhancing the adherence of said porous sponge to an applied tissue stably associated with at least one surface of said porous sponge, wherein said adherence-enhancing material is essentially free of a hydrogel forming component, and wherein the adherence-enhancing material is present in a grid pattern on the porous sponge.
A method of manufacturing a hemostatic composite sponge comprising
- providing a porous sponge of a matrix of a biomaterial;
- providing a material enhancing the adherence of said porous sponge to the applied tissue in the form of a suspension, a solution or powder, wherein said adherence-enhancing material is essentially free of a hydrogel forming component;
- and
- contacting the porous sponge and the adherence-enhancing material so that the adherence-enhancing material is stably associated with at least one surface of said porous sponge so that the hemostatic composite sponge is obtained,
- wherein the step of contacting the porous sponge and the adherence-enhancing material comprises first placing a grid onto the porous sponge and then distributing the adherence-enhancing material onto the porous sponge, such that the sponge is partially shielded from the adherence-enhancing material.
