Abstract: Soft embolic implants exhibiting secondary shapes are disclosed. Some of the embolic implants exhibit progressively increasing softness from the distal end to the proximal end of the coil. The embolic implants have a primary coil, an optional second coil, a shape wire, and a stretch resistant fiber disposed in the lumen of the primary coil. An optional distal support wire is also disclosed. The embolic implants include a proximal constraint assembly configured to be releaseably retained by a delivery device. Disposed near each end of some of the implants are elliptical hole washers through which the shape wire and the stretch resistant fiber are threaded. The embolic implants have a primary, linear configuration for delivery through an implant tool, and a secondary configuration after deployment from the implant tool. The secondary shape can be J-shaped, helical, spherical, complex, or a combination of shapes.

Abstract translation: 公开了具有二次形状的软栓塞植入物。 一些栓塞植入物从线圈的远端到近端呈现逐渐增加的柔软度。 栓塞植入物具有初级线圈，可选的第二线圈，形状线和设置在初级线圈的内腔中的抗拉纤维。 还公开了可选的远侧支撑线。 栓塞植入物包括构造成由递送装置可释放地保持的近端约束组件。 一些植入物的每个端部附近都设有椭圆形孔垫圈，形状线和抗拉纤维穿过该孔垫圈。 栓塞植入物具有用于通过植入物工具递送的主要的线性构造，以及在从植入物工具展开之后的次要构造。 二次形状可以是J形，螺旋形，球形，复合或形状的组合。
