3. What is Cochlear Implant ?
• The cochlear implant is an electronic device
that is implanted under the skin with
electrodes positioned in the cochlea to
stimulate the auditory nerve

4. The components which are essential in a
cochlear prosthesis system can be divided into 2
types -
a)External components
b)Internal components

5. Cochlear Ltd.

6. • Cochlear is a medical device company that
designs, manufactures and supplies the
Nucleus Cochlear Implant , the Hybrid
electro-acoustic implant and the BAHA Bone
Conduction implant
• Cochlear was formed in 1981 with finance
from the Australian Government to
commercialise the implants pioneered by
Dr. Graeme Clark.

9. INTRODUCTION
• Nucleus 7 is the world’s first and only Made for
iPhone cochlear implant sound processor. First for
iPhone, First for Android : the Nucleus Smart Apps
allows recipients to control and monitor their sound
processor with their smartphone.

12. Physical configuration The processing unit comprises:
• Two omni-directional microphones for receiving
sound.

RF emissions CISPR 11 Group 1 The Nucleus 7 Sound Processor uses RF
energy only for its internal function.
Therefore, its RF emissions are very low and
are not likely to cause any interference in
nearby electronic equipment.

25. Nucleus® Kanso® Sound Processor

26. How It Works:
• The external sound processor is worn over the ear. It
captures sound, then filters and processes the sounds,
turning it into digital code.
• The sound processor transmits the digitally-coded sound
through the coil on the outside of the head to the
implant.
• The internal implant converts the digitally-coded sound
into electrical impulses and sends them along the
electrode array that sits gently in the cochlea (the inner
ear).
• The implant’s electrodes stimulate the cochlea’s hearing
nerve, bypassing the damaged cells that cause hearing
loss, sending impulses to the brain where they are
interpreted as sound

28. Physical configuration
The processing unit comprises:
• Two omni-directional microphones for receiving sound.
• An internal telecoil for receiving magnetic fields radiated
by room loops.
• Custom analogue and digital integrated circuits with digital
signal processing (DSP) and bi-directional wireless
communication capabilities.
• A tri-colour visual indication of processor function or
problem.
• One button allowing user control of key features. The
batteries provide power to the processor, which transfers
energy and data to the implant.

29. Materials
• Processing unit: polyamide.
• Magnet casing is made of acrylonitrile butadiene
styrene (ABS).
Batteries
• The Kanso Sound Processor uses two high
power 675 (PR44) zinc air disposable batteries
designed for cochlear implant use
• Battery life of more than 16 hours for typical use
with zinc air batteries

30. Wireless communication link
• The remote control/remote assistant wireless
communication link operates in the 2.4 GHz
iSM band using GFSK (Gaussian frequency
shift keying) on 5 channels.
• The link uses a proprietary bi-directional
communication protocol and operates over a
distance of up to 2 metres from the processor.

32. Attach a SoftWear pad
• The Cochlear SoftWear™ pad is optional. if
you experience discomfort when wearing your
processor, then personn can attach this
adhesive pad to the back of your processor.

33. Attach a Safety Line
Standard and Long Safety Lines
• To reduce the risk of losing your processor,
• Patient can attach a Safety Line that clips onto
the clothing:
1. Nucleus Safety Line–standard length
2. Cochlear Safety Line (Long)

34. Safety Line–Short Double Loop
• To reduce the risk of losing your processor,
you can attach a Safety Line that clips into
your hair:

35. Wear the Headband
The Cochlear Headband is an optional
accessory that holds the processor in place on
your implant. This is useful for children or for
physical activities.

36. • Headband sizing
To choose a Headband, measure your head
circumference:
SiZE CIRCUMFERENCE
XXS 41-47 cm
M 52-58 cm
XS 47-53 cm
L 54-62 cm
S 49-55 cm

37. ELECTRODE

38. Slim Modiolar
• World’s thinnest full length perimodiolar electrode.
• The Slim Modiolar Electrode is the world’s thinnest
full length perimodiolar electrode designed for
consistent scala tympani placement and sits closest
to the hearing nerve to deliver optimal hearing
performance.
• It is reloadable, offers a smooth easy insertion and
can be inserted through round window (RW),
extended round window (ERW) or cochleostomy.
• The Slim Modiolar electrode combines the unique
benefits of a thin electrode with the perimodiolar
positioning closer to the spiral ganglion cells.

42. Cochlear Nuchleus Hybrid L24
Electrode
This electrode is for candidates who have good
low frequency hearing . It provides the
electrical stimulation in the basal section of
the cochlea , avoiding the apical region to
maximise the potential for acoustic
stimulation.
