Abstract:
1. A method for directing cell in-growth and controlled tissue regeneration in a tissue comprising covering said tissue present in a mammal with a multilayered collagen foil biomatrix comprising multiple layers of precipitated collagen fibrils that form stacked collagen fibril sheets packed tightly together and comprising pores that are isolated from one another and are not interconnected in a manner which traverses the collagen foil biomatrix and a surface of the collagen foil biomatrix is non-porous, wherein said tissue is selected from the group consisting of spinal column tissue, dura mater, and spinal nerves, wherein said covering of said tissue prevents post-surgical adhesion and fibrosis formation on a surface of said tissue by separating said tissue from adjacent tissues and wherein said covering directs cell ingrowth and controlled tissue regeneration in said tissue.
