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 means (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 means (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 means (22) from the carrier member.
A device for inserting an electrode array into a cochlea of a subject, the electrode array having an elongate carrier member and a removable means extending through the carrier member for at least a portion thereof, the device including a handle, an elongate positioning member mounted to the handle, an actuator member movable relative to the elongate positioning member, and at least one anchor member connected to the actuator member and engageable with the removable means, wherein on insertion of the electrode array into a subject's cochlea, the actuator member can be moved relative to the elongate positioning member to withdraw the removable means from the carrier member.
The device of any one of the preceding claims wherein the anchor member is positioned in the proximal portion or the distal portion of the positioning member.
The device of any one of the preceding claims wherein the anchor member is adapted to engage with a tie member extending from the removable means of the electrode array.
The device of any one of the preceding claims wherein the actuator member has a distal end adapted to engage with the electrode array.
The device of any one of the preceding claims wherein the actuator member comprises a slide member which is slidably movable along a length of the handle.
The device of any one of the preceding claims wherein the slide member is connected to the anchor member by a connector means.
