Method of achieving hemostasis

Abstract

The'method of achieving hemostasis in wounds, vascu lar grafts, vascular patches, cardiac valves and the like is described. Hemostasis is achieved in open wounds by topically administering chitosan, in liquid or powder form, to the wound. He‘mostasis is achieved in vascular grafts, vascular patches,- cardiac valves and areas to be sutured by either topically administering chitosan to the grafts, patches, valves and sutures or incorporating chitosan in the material of the grafts, patches, valves and sutures.
