METHOD FOR THE PRODUCTION OF CROSSLINKED AND OPTIONALLY SHAPED TISSUE WITH SELECTIVE ADJUSTMENT OF THICKNESS, SHAPE AND/OR FLEXIBILITY

A method for chemically crosslinking and optionally shaping (including thickness reduction) substantially non-cross-linked tissue, in particular biological tissue, using a permeable material layer. The method can be used in combination with a stepless pressure load/compression on the tissue, so as to always allow fluid transport into and out of the tissue to be treated under the chemical cross-linking; along the lines of drainage. The method can be carried out under different pressure loads/compressions, in particular in order to specifically influence the resulting tissue properties, and, for example, to bring about a homogeneous thickness distribution of the tissue and/or to deliberately and specifically place inhomogeneities, if desired. Furthermore, the method allows the introduction/imprinting of a consistent three-dimensional shape into the tissue to be treated, e.g. of inhomogeneities in the thickness of the tissue.
