Claims20
A hemostatic porous sponge comprising a matrix of oxidized cellulose and a bioadhesive material stably associated with at least one surface of said porous sponge, wherein said bioadhesive material is free of gelatin, said bioadhesive material is present in a range of 2 to 5 mg/cm2 of the oxidized cellulose, and said bioadhesive material is present in a grid pattern on the porous sponge.
A hemostatic porous sponge comprising a matrix of oxidized cellulose and a material enhancing the adherence of said 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 gelatin, said adherence-enhancing material is present in a range of 2 to 5 mg/cm2 of the oxidized cellulose, and the adherence-enhancing material is present in a grid pattern on the porous sponge.
A hemostatic porous sponge comprising a matrix of oxidized cellulose and a gelatin-free material enhancing the adherence of said sponge to an applied tissue stably associated with at least one surface of said porous sponge, wherein said gelatin-free material is present in a range of 2 to 5 mg/cm2 of the oxidized cellulose, wherein the gelatin-free material is present in an organized pattern on the porous sponge.
