    • A retrieval device (10) having a contracted state and an expanded state may include a sheath (12; 104), and at least three support members (26, 28, 30; 158, 160, 162) each having at least two lumens, a proximal end fixed to the sheath (12; 104), and a distal end movable relative to the sheath (12; 104). The retrieval device (10) may also include at least three movable members (18, 20, 22; 152, 154, 156) movable relative to the support members (26, 28, 30; 158, 160, 162). Each movable member (18, 20, 22; 152, 154, 156) may extend through a lumen of one support member of the at least three support members (26, 28, 30; 158, 160, 162) and through a lumen of a different support member of the at least three support members (26, 28, 30; 158, 160, 162).
    • 具有收缩状态和膨胀状态的取回装置(10)可以包括护套(12; 104)和至少三个支撑构件(26,28,30; 158,160,162),每个支撑构件具有至少两个流明, 固定到所述护套(12; 104)的近端,以及可相对于所述护套(12; 104)移动的远端。 所述取回装置(10)还可以包括相对于所述支撑构件(26,28,30; 158,160,162)可移动的至少三个可移动构件(18,20,22; 152,154,156)。 每个可移动构件(18,20,22; 152,154,156)可以延伸穿过至少三个支撑构件(26,28,30; 158,160,162)的一个支撑构件的内腔并且穿过所述至少三个支撑构件 所述至少三个支撑构件(26,28,30; 158,160,162)中的不同的支撑构件。
