    • A non covered stent is provided to improve convenience in a surgical operation by allowing the curled stent to be smoothly restored to its original normal shape after curling up an end portion of the stent. A non covered stent comprises: a first turn part(B1) including pluralities of peak portions(P1,P2) and valley portions(V1,V2) formed by bending a wire(W) in a zigzag shape along a circumferential surface of the stent, and first straight line portions(W1) connected between the peak portions and the valley portions; an interference turn part(B2) formed by second straight line portions(W2) to form pluralities of other peak portions and valley portions, the second straight line portions being bent in cross directions such that the second straight line portions are interfered with the first straight line portions; a cylindrical stent body(2) formed by hooking and longitudinally connecting the peak portions of the first turn part and those of the interference turn part to each other; and a lasso(4) formed along the circumference of the stent body in a state that the lasso is hooked to wires of interference positions at which the first and second straight line portions cross each other.
    • 提供非覆盖的支架以通过在卷曲支架的端部之后允许卷曲的支架平滑地恢复到其原始正常形状来改善手术操作的便利性。 非覆盖的支架包括:包括多个峰部(P1,P2)的第一匝部(B1)和沿支架的圆周表面弯曲线(W)形成的谷部(V1,V2) 以及连接在所述峰部和所述谷部之间的第一直线部(W1) 由第二直线部分(W2)形成的干涉转弯部分(B2),以形成多个其它峰部分和谷部分,所述第二直线部分在横向上弯曲,使得所述第二直线部分与所述第一直线部分 线部分 通过将第一匝部分的峰部与干涉匝部的峰部彼此钩挂并纵向连接形成的圆柱形支架体(2) 以及沿着所述支架主体的圆周形成的套索(4),所述套索以所述套索钩在所述第一直线部分和所述第二直线部分交叉的干涉位置的线的状态。
