    • A cochlear implant electrode assembly device (10) comprising an elongate electrode carrier member (11), a first stiffening element (15a), and a second stiffening element (15b). The carrier member (11) is made of a resiliently flexible first material and has a plurality of electrodes (12) mounted thereon. The carrier member (11) has a first configuration selected to allow it to be inserted into an implantee's cochlea (30), a second configuration wherein it is curved in shape to match a surface of the cochlea (30), and at least one intermediate configuration between the first and second configurations. Both the first and second stiffening elements (15a, 15b) are made of a material relatively stiffer than said the material and in combination bias the elongate member into the first configuration. If either the first stiffening element (15a) or the second stiffening element (15b) are removed, the elongate member (11) adopts the at least one intermediate configuration.
    • 一种包括细长电极载体构件(11),第一加强元件(15A)和第二加强元件(15b)的耳蜗植入电极组件装置(10)。 载体构件(11)由弹性柔性的第一材料制成并且具有安装在其上的多个电极(12)。 载体构件(11)具有被选择为允许其插入到植入物的耳蜗(30)中的第一构型,第二构造,其弯曲形状以匹配耳蜗(30)的表面,并且至少一个中间体 配置在第一和第二配置之间。 第一和第二加强元件(15a,15b)都由比所述材料相对更硬的材料制成并且将细长构件组合地偏压到第一构造中。 如果去除第一加强元件(15a)或第二加强元件(15b),细长构件(11)采用至少一个中间构造。
