Abstract
Provided is a flexible stent with which it is possible to further improve visibility of an impermeable member which is disposed upon a stent and to further improve operability of the stent. Provided is a flexible stent, comprising: a plurality of ring-shaped pattern bodieswhich have a wavy line-shaped pattern and are positioned side by side in an axial direction LD; and a plurality of connecting elementswhich connect the adjacent ring-shaped pattern bodies. When viewed in a radial direction RD which is perpendicular to the axial direction LD, a ring direction CD of the ring-shaped pattern bodiesis or is not oblique with respect to the radial direction RD. A plurality of impermeable memberswhich are highly impermeable to radiation are disposed upon and/or positioned in proximity to struts which configure the ring-shaped pattern bodiesand/or the connecting elements. The plurality of impermeable membersare arrayed regularly along one or more of the ring direction CD, an axial direction LD, or a circumference direction of the flexible stent.
