Abstract: There is a need to provide a collagen powder having desirable product characteristics, such as high fluid absorption capacity, while also having processing characteristics that allow commercial manufacturing and handling of the collagen powder. The present invention relates to a collagen powder, a method of manufacture thereof, and uses thereof. In particular, the present invention relates to a process for preparing a collagen powder, the process comprising the steps of providing a collagen source; adjusting the concentration of the collagen source; adjusting the pH of the collagen source; freezing the collagen source; dehydrating the frozen collagen; and degrading the dehydrated collagen to a powder.

Abstract: This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.
