发明名称 METHOD FOR REDUCING PARAVALVULAR LEAKS WITH DECELLULARIZED TISSUE
摘要 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.

主权项 1. 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, the method comprising: decellularizing the tissue (4); subjecting the decellularized tissue to a cross-linking solution (6) comprising glutaraldehyde; subjecting the tissue to a shape- and structure-stabilizing step (7, 8, 9), in which the tissue is exposed to a first solution (7) containing glycerol and is exposed to a second solution (8) containing polyethylene glycol; and drying the tissue after the shape- and structure-stabilizing step.
