The present invention provides a 2-way air flow type dispenser for spraying powder and a powder sprayer including the same. The present invention adopts a 2-way air flow manner in which an air flow causing the powder to be sprayed and an air flow causing the powder to be transferred from a container to a spraying nozzle are separately formed, thereby enabling the smooth spraying of the powder.

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.
