    摘要: The present invention describes a deposition method for applying an active ingredient onto an endoprosthesis with a thin polymer coating. By means of the inventive deposition method which can be carried out in a technically easy way it is possible to bring about a slow and largely constant active ingredient release, as shown in III. 1 using tretinoin as the example. Since further processing steps are not necessary after the application of the active ingredient(s), no destruction of the active ingredient by the application of a second polymer coating, for example, has to be feared. Thus, relatively unstable active ingredients, such as tretinoin, can also be applied onto the endoprosthesis without any problems.
