Abstract

A method for preparing tissue, in particular pericardial tissue, in particular for use as a sealing means for a heart valve prosthesis for paravalvular leaks, characterised in that the tissue, in particular pericardial tissue, is decellularized (4), subjected to a cross-linking (6) with a glutaraldehyde-containing solution, and subjected to a shape- and a structure-stabilising step (7, 8, 9). The invention also relates to a heart valve prosthesis.
