摘要： A stent (1) having a generally tubular body formed of annular units with a plurality of cells and extendable in a radial direction from the inside thereof, wherein the annular units (4) are formed by vertically connecting the plurality of cells (6) and a plurality of the connected cells are arranged so as to surround the center axis (C1) of the stent forming the tubular body, the annular unit is arranged in the axial direction of the stent, the annular units are connected to each other at least at one position through a connection part (5), the connection part is formed of a curved part (8) having two or more arcs and a generally straight part (7) continued to the curved part, the cells are arranged by three to eight units per 10 mm in length of the stent, and the ratio of the axial length (5L) of the connection part in stent axial direction to that (6L) of the cells in stent axial direction is set to 100 to 50 to 100, whereby a high flexibility and a radiation support force can be sufficiently assured and a vasodilating capability can be increased to suppress a fore-shortening and a flare event.

摘要： A stent (1) having a generally tubular body formed of ring units formed of a plurality of cells each and being expandable in the radius direction thereof from inside, wherein each ring unit (4) is constituted of the plurality of cells (6) connected to one another above and below and arranged so as to surround the center line (C1) of the stent forming said tubular body, the ring units are arranged in the axial direction of the stent, ring units are connected through at least one site with connector portions (5), each connector portion is formed of curved portions (8) having at least 2 arches and a generally linear portion (7) continued thereto and therefrom, 3 to 8 cells are arranged in the axial direction of the stent per 10 mm of the length of the stent, and the ratio of the length (6L) of the cell in the axial direction of the stent and the length (5L) of the connector portion in the axial direction of the stent is determined such that on the basis that when the length of the cell in the axial direction of the stent is taken as 100, the length of the connector portion in the axial direction of the stent is 50 to 100, thereby high flexibility and radial sustaining force are secured, the stent is improved in capability of dilating a blood vessel, and foreshortening and a flare phenomenon can be prevented.
