WIPO Patent Application WO/2018/066568
Kind Code:
A1
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 11, comprising: a plurality of ring-shaped pattern bodies 13 which have a wavy line-shaped pattern and are positioned side by side in an axial direction LD; and a plurality of connecting elements 15 which connect the adjacent ring-shaped pattern bodies 13. When viewed in a radial direction RD which is perpendicular to the axial direction LD, a ring direction CD of the ring-shaped pattern bodies 13 is or is not oblique with respect to the radial direction RD. A plurality of impermeable members 31 which are highly impermeable to radiation are disposed upon and/or positioned in proximity to struts which configure the ring-shaped pattern bodies 13 and/or the connecting elements 15. The plurality of impermeable members 31 are arrayed regularly along one or more of the ring direction CD, an axial direction JD, or a circumference direction of the flexible stent.
