Abstract
A method of forming a collagen-thrombin hemostatic composition is comprised of forming a homogeneous aqueous admixture of collagen and thrombin at a basic pH and lyophilizing the collagen-thrombin admixture to form a stable collagen sponge having thrombin therein. The collagen utilized in the process is absorbable when placed in vivo. Additionally, a lyophilized collagen product is comprised of collagen which is absorbable when placed in vivo and thrombin distributed within the collagen. The collagen product is storage stable.
