ABSTRACT:
A stent is a tubular member comprising cylindrical lumen size-holding portions1for holding a lumen of a living body open, and connecting portions2for longitudinally connecting the lumen size-holding portions1adjacent to one another. The lumen size-holding portions1are configured into repeated patterns running vertically in the developed conditions thereof. Each of the repeated patterns comprises a first curved pattern portion11having axis extending in a lateral direction and second and third curved pattern portions12and13having axes extending in vertical directions. The upper and lower first curved pattern portions11adjacent to one another are connected at one end thereof by the second curved pattern portion12, and at the other end by the third curved pattern portion13. 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.
