The invention relates to the field of biotechnology and medicine, more precisely, to manufacturing technique of implantable medical devices (stents) containing organic lanthanum compound-based X-ray contrast agents distributed within the coating. The objective of this invention is the development of a biocompatible (and biodegradable) polymeric coating with glycolane on the surface of polymeric biodegradable vascular stents and other polymeric implants, which ensures, by means of introduction into a stent, satisfactory radiopacity both during stent installation in a patient and after installation, with a simultaneous additional positive effect provided by therapeutic properties of glycolane.
