Abstract
A stent able to minimize occurrences of strain and stress concentration in a drug coat layer upon expansive deformation of the stent in a radial direction to avoid the possibility of the drug separating from the stent, includes a stent body and a drug coating layer coated on the outside surface of the stent body so that the thickness of the drug coating layer gradually decreases toward a bent portion of the stent.
