The aim of the invention is to design a vessel stent in which the risk of restenosis is reduced without having to use anti-proliferative agents. Said aim is achieved by using a support made of a dimensionally stable material and one or more layers of a material that is resorbable in physical conditions and is based on crosslinked gelatin, said layer/s being disposed in at least some areas of the support. The adhesion between the support and the layer and/or between the individual layers can be eliminated.
La présente invention concerne un stent qui permet de réduire les risques de resténose sans qu'il soit pour autant nécessaire d'avoir recours à des principes actifs anti-prolifération. A cet effet sont employés selon l'invention un support en matériau indéformable et une ou plusieurs couches d'un matériau résorbable dans les conditions physiologiques, à base de gélatine réticulée, la ou les couches étant appliquée(s) au moins par zones sur le support, l'adhérence entre le support et la couche et/ou entre les couches individuelles pouvant être supprimée.
