Abstract
Disclosed is a biocompatible, hemostatic, cross-linked gelatin composition comprising a biocompatible material comprising cross-linked gelatin and a sufficient amount of wetting agent to permit uniform wetting of the sponge in the presence of an aqueous solution.
Claims8
A hemostatic compound delivery system, comprising:
- a preformed cross-linked gelatin sponge comprising a wetting agent, wherein the wetting agent is coated on at least a substantial portion of the surface of the preformed cross-linked gelatin sponge;
- wherein the wetting agent decreases hydration time of the preformed cross-linked gelatin sponge and the wetting agent is soluble in a non-aqueous solvent;
- a saline solution;
- and
- a syringe assembly,
- wherein the wetting agent is coated on at least a substantial portion of the surface of the preformed gelatin sponge by soaking the preformed gelatin sponge in a coating solution including the wetting agent and the non-aqueous solvent.

A method for hydrating a biocompatible, hemostatic, preformed cross-linked gelatin composition, comprising the steps of:
- providing an aqueous solution;
- providing a preformed cross-linked gelatin composition including a preformed cross-linked gelatin sponge and a wetting agent, wherein the wetting agent is coated on at least a substantial portion of the surface of the preformed cross-linked gelatin sponge and decreases hydration time of the preformed cross-linked gelatin sponge;
- and
- contacting the preformed cross-linked gelatin composition with the aqueous solution,
- wherein the wetting agent is coated on at least a substantial portion of the surface of the preformed gelatin sponge by soaking the preformed gelatin sponge in a coating solution including the wetting agent and a non-aqueous solvent,
- further wherein the preformed gelatin sponge includes a sufficient amount of wetting agent to permit uniform wetting of the gelatin in the presence of the aqueous solution.
