Abstract
A device (10) used for inserting an electrode array (15) into a cochlea of a subject. Particularly, the device (10) is adapted for insertion of electrode arrays (15) having an elongate carrier member (21) and a removable stylet (22) extending through the carrier member (21). The device includes a handle (11), an elongate positioning member (12) mounted to the handle (11), an actuator member (17) movable relative to the elongate positioning member (12), and at least one anchor member (16) connected to the actuator member (17) and engageable with the removable stylet (22). On insertion of the electrode array (15) into a subject's cochlea, the actuator member (17) can be moved relative to the elongate positioning member (12) to withdraw the removable stylet (22) from the carrier member.
