The present disclosure relates to methods of manufacturing and passivating stents and other implantable medical devices including one or more attached radiopaque markers. In one embodiment, the method includes providing a metallic implantable medical device body without any radiopaque marker(s) attached thereto, primary electropolishing the device body without any markers attached thereto, attaching one or more radiopaque markers to the device body, and lightly electropolishing the device including device body and attached radiopaque markers. Light electropolishing removes no more than about 5% by weight of the device (i.e., the device body and attached marker(s)). Light electropolishing passivates the exposed surfaces of the device body and markers, while also providing electropolishing to the region of any welds where the radiopaque marker(s) is/are attach to the device body.
