A stent that can further reduce the incidence of repeated stenosis (restenosis) that has been experienced in conventional stents is provided. Onto the outer surface of a stent body, a structure for cutting body tissues and the like is disposed so that during stent expansion in the outward radial direction and placement, the body tissues, such as blood vessels, are cut. Thus, the stress and unrestricted damage applied to body tissues such as blood vessels can be reduced, and restenosis can be suppressed. By coating the stent with a drug, a stent having enhanced effects can be provided. |
