摘要：
The present invention relates to a stent having a functional material coated on a cell space (safe coating space) thereof. The stent of the present invention, as a stent having a space for mounting and coating drugs and other materials for expanding the functions of the stent, is highly feasible as an actual product in consideration of the structure, transfer device, and manufacturing process of the stent as a whole, and secures a coating space (safe coating space) of a functional material in a cell of the stent through quantitative and qualitative modelling. Since an additional increase in volume does not occur even when the stent is press-mounted in a transfer device as a result of mounting a radio marker or a drug in the coating space, the stent of the present invention has excellent radio opacity without obstructing the loading and deployment of the stent, and may stably mount a great amount of a functional drug.
