Abstract

A method for preparing tissue, in particular pericardial tissue, in particular for a heart valve prosthesis, the method including: decellularizing the tissue; subjecting the decellularized tissue to a cross-linking solution including glutaraldehyde; subjecting the tissue to a shape- and structure-stabilizing step, in which the tissue is exposed to a first solution containing glycerol and is exposed to a second solution containing polyethylene glycol; and drying the tissue after the shape- and structure-stabilizing step.
