Abstract
The invention concerns a method for coating a vascular endoprosthesis, wherein the vascular endoprosthesis is at least partially wetted with a first solution of an active ingredient and the areas of the vascular endoprosthesis at least partially wetted with the first solution of the active ingredient are at least partially wetted with a liquid containing water and/or at least an alcohol. The additional wetting with a liquid containing water/alcohol imparts a different consistency to the active ingredient layer, specifically making it is less transparent and lacquer-like and more chalklike and opaque. It has been found that such an active ingredient layer provides better transfer of the active ingredient to the blood vessels in which the vascular endoprosthesis is implanted.
