Abstract
A cochlear implant system includes a cochlear electrode array which has a flexible body with a distal end, a plurality of electrodes supported along a length of the flexible body, and a lumen formed in the flexible body. The cochlear implant system also includes a stiffening stylet which is fully inserted into the lumen prior to insertion of the electrode array into the cochlea. The stiffening stylet is configured such the stylet does not extend to the distal end of the flexible body and remains stationary within the lumen to prevent buckling of the electrode array during insertion of the electrode array through a cochleostomy and into the cochlea. The stiffening stylet is configured to be withdrawn from the lumen after the electrode array is positioned within the cochlea. A method for implanting an electrode array into a cochlea is also provided.
