    摘要： A composite stylet for facilitating insertion of an implantable electrode array into either a left or right cochlea comprises a composite having a glass transition temperature between room temperature and body temperature. While relatively stiff and straight at room temperature, the composite stylet is slidably inserted into a longitudinal lumen of the electrode array. The electrode array is then inserted into the cochlea. As the composite stylet within the electrode array warms to body temperature, it becomes compliant, allowing the electrode array to assume a spiral shape. The proximal end of the composite stylet, which is not inserted into the body, retains its stiffness to aid the implanter in inserting the electrode array.

    摘要翻译： 用于促进可植入电极阵列插入左耳蜗或右耳蜗的复合探针包括具有室温和体温之间的玻璃化转变温度的复合物。 虽然在室温下相对刚性和直线，但是复合探针可滑动地插入电极阵列的纵向内腔中。 然后将电极阵列插入耳蜗。 由于电极阵列内的复合管心针加热到体温，所以它变得顺从，允许电极阵列呈现螺旋状。 未插入到主体中的复合管心针的近端保持其刚度以帮助注入机插入电极阵列。
