Abstract
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.
