Exemplary systems for loading a pre-curved electrode array onto a stylet include a loading tool and a stylet retainer. The loading tool includes a docking assembly comprising a plurality of wing members that form a receptacle configured to receive a proximal portion of the stylet, a channel assembly comprising a channel configured to receive and allow passage therethrough of the pre-curved electrode array, the channel further configured to receive a distal portion of the stylet, and a connecting member configured to connect the channel assembly to the docking assembly. The stylet retainer is configured to couple to the loading tool to retain the stylet within the loading tool while the pre-curved electrode array is loaded onto the stylet. Corresponding methods are also described.
