Die Erfindung betrifft ein Verfahren zum Herstellen eines Implantats, welches insbesondere als Wundauflage ausgebildet ist. Das Implantat besteht aus einem Flächengebilde aus Magnesium, welches in einem Kollagenvlies eingebettet ist.A wound dressing and a method for production thereof. The wound dressing includes a collagen-containing sheet-like structure, which is made of magnesium or a magnesium alloy. The sheet-like structure has openings and is embedded in a collagen-containing sheet-like structure. The wound dressing is embodied as a geometrically stable bioresorbable membrane and includes a support made of a collagen membrane, on which the collagen-containing sheet-like structure is arranged.L'invention concerne un procédé de production d'un implant qui se présente en particulier sous la forme d'un pansement. Ledit implant se compose d'une structure plane en magnésium qui est noyée dans un non-tissé en collagène.
