The invention relates to a special type of bioresorbable metal stent with controlled resorption owing to a coating with a special polymer, guaranteeing a controlled resorption of the coated endoprothesis after implantation into a blood vessel. The resorbable implant consists of a magnesium alloy that is provided with a biodegradable coating. Said biodegradable coating consists preferably of biodegradable polymers and may additionally contain at least one pharmacologically active substance such as an antiproliferative, antimigration, antiangiogenic, anti-inflammatory, antiphlogistic, cytostatic, cytotoxic and/or antithrombotic agent, anti-restenosis agents, corticoids, sex hormones, statins, epothilones, prostacyclins and/or angiogenesis inducers. |
