Abstract
The present invention is directed to hemostatic compositions comprising at least partially integrated agglomerated ORC fibers, fibrinogen, and thrombin and methods of forming a powdered hemostatic composition, comprising the steps of: forming a suspension of a mixture comprising particles of fibrinogen, thrombin, ORC fibers in a non-aqueous low boiling solvent, agitating and shearing said suspension in a high shear mixing reactor, adding water to allow particles to agglomerate, allowing the non-aqueous solvent to evaporate, drying and sieving the composition; and thus forming the powdered hemostatic composition.
