Abstract
A device, system and method for inserting a pre-curved electrode array (100) held in a substantially straight configuration by a straightening member (101) into a cochlea of a subject. As the electrode array (100) is inserted into the cochlea by the device, the straightening member (101) is held by the device such that the electrode array (100) advances off the straightening member (101) such that it is free to take on its pre-curved configuration in the cochlea of the subject.

1-49. (canceled)
A cartridge for mounting an electrode array on an electrode array insertion device, comprising:
- an elongate body having first and second ends and a lumen extending therethrough, wherein said elongate body is configured to receive an electrode array in said lumen;
- and
- a window in a sidewall of said elongate body configured to allow viewing of a portion of the electrode array when the electrode array is positioned in said elongate body.
A kit comprising:
- a straightening member;
- a pre-curved electrode array configured to be maintained in a substantially straight configuration when said straightening member is positioned along a substantial length of said electrode array;
- and
- a cartridge comprising:
- an elongate body having first and second ends and a lumen extending therethrough, wherein said elongate body is configured to receive said electrode array in said lumen;
- and
- a window in a sidewall of said elongate body configured to allow viewing of a portion of said electrode array when said electrode array is positioned in said elongate body.
A system for inserting an electrode array into a cochlea of a subject, said system comprising:
- a straightening member;
- a pre-curved electrode array configured to be maintained in a substantially straight configuration when said straightening member is positioned along a substantial length of said electrode array;
- a cartridge configured to receive said electrode array;
- and
- an insertion device configured to receive at least a portion of said cartridge when said electrode array is positioned therein;
- wherein said insertion device is configured to effect movement of said electrode array from a first position to a second position relative to the insertion device and to substantially prevent said straightening member from moving with said electrode array from said electrode array's first position to said electrode array's second position.
