Abstract
A collagenous tissue preparation suitable for homotransplantation or heterotransplantion. The preparation is a non-resorbable, non-antigenic collagenous material which retains the natural structure and original architecture of the natural tissue. The material is substantially free of non-fibrous tissue proteins, glycoproteins, cellular elements and lipids. The tissue preparation is recolonized by host cells and revascularized after implantation into the host.
Claims7
A non-resorbable, substantially non-antigenic collagenous fibrous tissue preparation of human or animal tissue origin, which is suitable for homo- or heterotransplantation as a permanent repair for cutaneous wounds and soft tissue injuries, which preparation retains the natural structure and original architecture of said human or animal tissue, is substantially free of non-fibrous tissue proteins and glycoproteins, is substantially free of cellular elements, is substantially free of lipids and lipid residues and is non-cytotoxic, wherein said preparation is capable when implanted of being recolonized by host cells and revascularized while being resistant to calcification.
A preparation as claimed in any one of the preceding claims when in the form of a sheet.
