PURPOSE: A stent for treating stenosis is provided to effectively disperse pressure applied from the outside of the stent by deforming the stent into a hexagon form when the diameter of the stent is expanding. CONSTITUTION: A stent (10) for treating stenosis includes an upper curved unit, a lower curved unit, and plural supporting units. Plural curves are formed on the upper curved unit. The lower curved unit is separated from the upper curved unit to the longitudinal direction of the stent, and has a vertically symmetrical shape with the upper curved unit. The supporting units connect the upper and lower curved units. The upper and lower curved units form one cell by being connected by the supporting units. One cell shares the supporting units with another cell, and forms a successive cell form along the circumference direction of the stent. |
