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 .
