Abstract
A hemostatic device formed of collagen particles and methods for producing and using the hemostatic device to control bleeding are provided. The collagen particles of the hemostatic device have a hemostatic activity that is equivalent to the hemostatic activity of the collagen particles from which the hemostatic device is formed. More preferably, the hemostatic devices are formed of Avitene® flour and the collagen particles of the hemostatic devices of the invention have a hemostatic activity equivalent to the hemostatic activity of Avitene® flour. The hemostatic devices optionally include hemostatic agents and/or therapeutic agents, to further promote hemostasis and wound healing.
