Technical Specifications
® 5 Cochlear Implant (CI512)
From the company with the industry’s best implant reliability record 1-3 - built on over 25 years of
experience and developed in close collaboration with surgeons around the world.
The new Nucleus 5 Cochlear Implant is:
• The world’s thinnest cochlear implant in an ergonomic, sleek shape.
• Stronger and designed to be impact resistant.
• Precise stimulation designed for unsurpassed hearing performance.
Components of the Nucleus 5 Cochlear Implant
Implant coil, enabling telemetry.
New, thinner and more flexible coil
than our previous generation and a
thinner removable magnet.
Receiver stimulator in titanium casing,
designed for impact resistance.
Symmetrical, side by side exit leads
from main casing. Lower profile and
designed for increased robustness.
Easily placed in the left or right ear.
With a removable magnet, patients
can access MRI scans up to 1.5 Tesla
for high quality medical views with
minimal image obstructions.
Overall dimensions of the Nucleus 5 Cochlear Implant
The world’s thinnest cochlear implant - only 3.9 mm thin.

Two extracochlear electrodes for
different stimulation modes.
22 half-banded platinum electrode
contacts, provide focused stimulation
to the spiral ganglion cell region of the
cochlea for lower T & C levels. 4
Features the highest density of electrode
contacts and patented non-uniform
electrode spacing designed to better
target the spiral ganglion cells – from
base to apex. 5
When used with Cochlear’s AOS
surgical technique, it is designed to
help protect delicate cochlear structures
crucial for hearing.

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

Not all patients with hearing loss are candidates for cochlear implantation. Cochlear
implantation is a surgical procedure, and carries with it the risks typical for surgery. For
complete information regarding indications, warnings and adverse effects,
