Abstract
A stent is a tubular member comprising cylindrical lumen size-holding portionsfor holding a lumen of a living body open, and connecting portionsfor longitudinally connecting the lumen size-holding portionsadjacent to one another. The lumen size-holding portionsare configured into repeated patterns running vertically in the developed conditions thereof. Each of the repeated patterns comprises a first curved pattern portionhaving axis extending in a lateral direction and second and third curved pattern portionsandhaving axes extending in vertical directions. The upper and lower first curved pattern portionsadjacent to one another are connected at one end thereof by the second curved pattern portion, and at the other end by the third curved pattern portion. The stent is excellent in flexibility and trackability to lumens. Further, the stent is capable of being passed through three-dimensionally meandering lumens and possesses a sufficient strength for holding a widened size of a lumen.
