RECEIVER STIMULATOR<br />
General Features<br />
• Weight - 8.8 g (incl. electrode array).<br />
• Designed to be impact resistant and 2.5x stronger *<br />
MRI<br />
• MRI safe at 1.5 Tesla with magnet removed<br />
(for further details refer to the Surgeon’s guide).<br />
ELECTRODE ARRAY<br />
Contacts<br />
• 22 half-banded platinum electrodes - molded in a<br />
perimodiolar shape.<br />
• Electrode contacts arranged in non-uniform spacing from<br />
0.4 to 0.8 mm and spaced over 15 mm active array.<br />
• More robust lead designed to withstand the rigors of<br />
implantation for a lifetime.<br />
General Features<br />
• Platinum, arrow stylet - holds the electrode straight<br />
for insertion with Advance Off-Stylet (AOS )<br />
surgical technique.<br />
• AOS surgical technique and Softip electrode<br />
- minimize lateral wall insertion force.<br />
• Two extracochlear electrodes - one titanium plate<br />
at the implant receiver stimulator and a separate<br />
0.6 mm diameter cylindrical electrode.<br />
• A white marker between 10th and 11th array contact<br />
- indicates insertion depth when the tip is close to the<br />
lateral wall of the cochlea.<br />
Dimensions<br />
ARROW STYLET<br />
• 19 mm intracochlear length including Softip.<br />
• Electrode diameter at apical end - 0.5 mm.<br />
• Electrode diameter at basal end - 0.8 mm.<br />

Not all patients with hearing loss are candidates for cochlear implantation. <strong>Cochlear</strong><br />
implantation is a surgical procedure, and carries with it the risks typical for surgery. <strong>For</strong><br />
