Abstract
A stent configuration wherein particles of radiopaque material contained within a polymeric binder is coated onto a stent core structure to enhance the radiopacity of the stent. The stent is initially formed and rendered radiopaque after all surfaces are coated with the radiopaque coating. The amount of particles of radiopaque materials can be varied (by volume) within the binder to either increase or decrease the radiopacity of the binder coating in order to obtain an optimal amount of radiopacity to the stent. The thickness of the coating also can be varied to fine tune the radiopacity of the stent.
