Abstract:
1. A method of repairing and regenerating dura mater tissue in a mammal comprising attaching a collagen foil to the dura matter tissue, wherein the collagen foil comprises a non-naturally occurring biomatrix of multiple layers of precipitated collagen fibrils having a diameter of between 10 to 300 nanometers that are not cross-linked by chemicals or radiation, wherein the biomatrix comprises pores that are isolated from one another and are not interconnected in a manner which traverses the collagen foil, wherein the multiple layers of precipitated collagen fibrils form stacked collagen fibril sheets packed tightly together with interstices there between, and wherein the multiple layers of precipitated collagen fibrils of the collagen foil have an ultimate tensile force of between 0.5 Newtons/cm-strip and 30 Newtons/cm-strip.
