ABSTRACT:
An insertion tool uses a stylet wire to help guide an electrode system into a cochlea. The insertion tool includes three main elements or parts: a handle, a guide and a slider. The handle is made from light stainless steel tube flattened in front with a machined slot. The guide consists of a plurality of metal tubes, fixed to each other within a holding bracket. In one embodiment, the slider includes a stabilizer wire, a long stylet wire, and a short stylet wire. During the assembly process, the stabilizer and stylet wires are inserted into respective tubes of the guide and the end of the stabilizer wire is bent to form an offset. The electrode system is loaded onto the tool by inserting the short stylet wire into a holder that supports the electrode lead.
