MED-EL <strong>El</strong>ectrode Arrays<br />
Designed for Atraumatic Implantation<br />
Providing Superior Hearing Performance
World’s Largest Selection of <strong>El</strong>ectrodes<br />
for a Variety of Cochlear Duct Lengths (CDLs) 1,3<br />
Cochleae may differ significantly in size <strong>and</strong> shape<br />
from one another as can individual cochlear duct<br />
lengths. MED-EL offers the largest selection of<br />
electrode arrays. Each implant recipient can be<br />
sure <strong>to</strong> receive the <strong>best</strong> possible electrode array<br />
for their unique cochlear ana<strong>to</strong>my.<br />
Complete Cochlear Coverage (CCC) 2, 5<br />
Complete Cochlear Coverage means stimulating the<br />
cochlea from the base <strong>to</strong> the apical region in order<br />
<strong>to</strong> stimulate a maximum number of nerve fibres.<br />
Stimulation of the entire frequency range with a<br />
deeply inserted, long array provides the implant user<br />
with the <strong>best</strong> possible outcomes in speech<br />
performance measures <strong>and</strong> in sound quality.<br />

Designed Especially for Neurofibroma<strong>to</strong>sis Type II<br />
ABI is a solution for individuals with hearing loss due<br />
<strong>to</strong> a non-functioning audi<strong>to</strong>ry nerve (Neurofibroma<strong>to</strong>sis<br />
Type II). Bypassing both the inner ear <strong>and</strong> the audi<strong>to</strong>ry<br />
nerve, the MED-EL ABI stimulates the cochlear nucleus<br />
(CN) <strong>and</strong> provides users with a variety of hearing<br />
sensations <strong>to</strong> assist with sound awareness <strong>and</strong><br />
communication.<br />

Featuring 12 contacts arranged on a soft,<br />

MED-EL <strong>El</strong>ectrode Arrays<br />
Designed for Atraumatic Implantation<br />
Providing Superior Hearing Performance 4,6,7<br />
MED-EL is the leader in providing soft, <strong>flexible</strong><br />
electrode arrays which ensure maximum protection<br />
of the delicate structures in the cochlea. Preserving<br />
residual hearing enables users <strong>to</strong> benefit from future<br />
technologies <strong>and</strong> therapies.<br />
Wave-Shaped Wires<br />
The electrode arrays feature ultra<strong>flexible</strong> wave-shaped<br />
platinum-iridium wires. This wire design is the key <strong>to</strong><br />
making a MED-EL electrode array the world’s most<br />
<strong>flexible</strong> <strong>and</strong> atraumatic. Minimising trauma during<br />
electrode insertion maximises the benefit <strong>to</strong> the<br />
patient. Wave-shaped wires significantly reduce rigidity<br />
in comparison <strong>to</strong> a straight-wire design. Benefits<br />
include preserving the integrity of intraneural tissue<br />
targeted for electrical stimulation.<br />
FLEX TIP TECHNOLOGY<br />
The FLEx tip of the electrode<br />
array is designed for<br />
atraumatic insertion <strong>and</strong><br />
protection of the delicate<br />
neural structures of the<br />
cochlea.<br />
Optimal Number of Contacts<br />
MED-EL’s electrode design philosophy dictates a careful<br />
balance between the maximum number of electrode<br />
contacts <strong>and</strong> minimised channel interaction. Channel<br />
interaction negatively impacts performance. Each<br />
electrode array contains the optimal number of<br />
contacts for stimulation of nerve fibres leading <strong>to</strong><br />
<strong>best</strong> performance. Optimal number <strong>and</strong> spacing of<br />
electrode contacts also significantly reduces rigidity;<br />
allowing for gentle insertion without damaging the<br />
delicate cochlear structures.<br />
FLEX Tip Technology<br />
The unique FLEx tip features single electrode contacts<br />
on the leading end <strong>to</strong> further increase mechanical<br />
flexibility. Softness <strong>and</strong> flexibility allow insertion in<strong>to</strong><br />
the apical region.<br />
WAVE-SHAPED WIRES<br />
Wavy instead of straight,<br />
the wires of the electrode<br />
array are particularly soft<br />
<strong>and</strong> <strong>flexible</strong>.<br />
OPTIMAL NUMBER<br />
OF CONTACTS<br />
Achieving optimal balance<br />
between the number of<br />
contacts <strong>and</strong> the appropriate<br />
distance between them<br />
increases flexibility <strong>and</strong> limits<br />
channel interactions.
FLEx SOFT<br />
A 31mm electrode array<br />
featuring FLEx tip technology<br />
for increased mechanical<br />
flexibility <strong>and</strong> enabling CCC.<br />
FLEx 28<br />
A 28mm electrode array suitable<br />
for 96% of all normal cochlear<br />
duct lengths featuring FLEx tip<br />
technology. Optimised for<br />
insertion in<strong>to</strong> the apical<br />
region (CCC).<br />
FLEx 24<br />
A 24mm electrode array featuring<br />
FLEx tip technology <strong>and</strong> designed<br />
for combined <strong>El</strong>ectric Acoustic<br />

less than 1.5 turns.<br />
FLEx 24 is formerly known as the FLEx EAS .<br />
FLEx 20<br />
NEW<br />
A 20mm electrode array featuring<br />
FLEx tip technology <strong>and</strong> designed <strong>to</strong><br />
be used in cases of partial deafness<br />
or for other specific needs or<br />
surgical preferences.<br />
