    • A vaso-occlusive device includes a coil having a proximal end and a distal end, wherein the coil comprises a helically wounded elongated member having a core and an outer layer, the outer layer being made from a metal or alloy, and has a stiffness that is different from a stiffness of the core. A vaso-occlusive device includes a first coil and a second coil, wherein the first and the second coils are coupled to each other such that at least one loop from the first coil is between two adjacent loops from the second coil, and wherein the first coil is made from a first material, and the second coil is made from a second material that is stiffer than the first material. A vaso-occlusive device includes an outer coil having a plurality of loops that define a lumen therethrough, and an inner coil located within the lumen of the outer coil, wherein the outer and inner coils are each made from a metal or an alloy, such as platinum or a platinum-tungsten alloy.
    • 一种血管闭塞装置包括具有近端和远端的线圈,其中所述线圈包括具有芯和外层的螺旋形受伤的细长构件,所述外层由金属或合金制成,并且具有刚度 与芯的刚度不同。 一种血管收缩装置包括第一线圈和第二线圈,其中第一线圈和第二线圈彼此耦合,使得来自第一线圈的至少一个回路位于来自第二线圈的两个相邻回路之间,并且其中第一线圈 线圈由第一材料制成,并且第二线圈由比第一材料更硬的第二材料制成。 一种血管闭塞装置包括具有限定通过其中的腔的多个环的外部线圈和位于外部线圈的内腔内的内部线圈,其中外部线圈和内部线圈均由金属或合金制成,例如 作为铂或铂 - 钨合金。
