Abstract

A radiopaque marker for inclusion within an implantable medical device (IMD) may comprise one or more radiopaque articles selected from a predetermined set of radiopaque articles. The one or more radiopaque articles may be carried by an object formed of or including, a desiccant. The predetermined set of radiopaque articles may undergo a single qualification process that approves the use of any combination of one or more of the articles as a radiopaque marker within an IMD. This allows a potentially-limitless number of markers to be made available based on a single qualification process. The radiopaque marker may serve to provide information such as the make, model, and feature set of the device.
