The invention is related to a biodegradable stent for vascular placement comprising, a tubular biodegradable metal structure, a biodegradable organic layer covering the surfaces of the structure, and optionally a biodegradable polymer coating covering the organic surface layer. The organic layer is a derivative of a monomer vapor injected plasma and is applied in a plasma enhanced chemical vapor deposition process. Thereby the biodegradable organic layer is an organosilane layer and the biodegradable polymer coating contains a therapeutic drug.
