Abstract
The present invention provides a hemostatic composite sponge comprising oxidized cellulose and an essentially gelatin-free bioadhesive material stably associated with said sponge and present in an organized pattern on said sponge.
Claims26
A method for treating an injury in a patient, the method comprising:
- providing a hemostatic porous composite sponge, wherein the hemostatic porous composite sponge comprising a matrix of oxidized cellulose and a bioadhesive material stably associated with at least one surface of the hemostatic porous composite sponge, wherein the bioadhesive material is free of gelatin, the bioadhesive material is present in a range of 2 to 50 mg/cm2 of the oxidized cellulose, and the bioadhesive material is present in a grid pattern on the hemostatic porous composite sponge;
- administering the hemostatic porous composite sponge to a site of the injury;
- and
- maintaining the hemostatic porous composite sponge to the site of the injury for a pharmaceutically sufficient amount of time so that the injury is treated.

A method for treating an injury in a patient, the method comprising:
- providing a hemostatic porous composite sponge, wherein the hemostatic porous sponge comprising a matrix of oxidized cellulose and a material enhancing the adherence of the hemostatic porous composite sponge to an applied tissue stably associated with at least one surface of the hemostatic porous composite sponge, wherein the adherence-enhancing material is essentially free of gelatin, the adherence-enhancing material is present in a range of 2 to 50 mg/cm2 of the oxidized cellulose, and the adherence-enhancing material is present in a grid pattern on the hemostatic porous composite sponge;
- administering the hemostatic porous composite sponge to a site of the injury;
- and
- maintaining the hemostatic porous composite sponge to the site of the injury for a pharmaceutically sufficient amount of time so that the injury is treated.
