MED-EL offers the broadest spectrum of different electrode arrays in the industry. They are each designed to match specific clinical requirements. The wide variety of electrode arrays enables surgeons to select the optimal solution for each individual’s ear including options for individuals presenting with cochlear ossification or with residual hearing.
The ability to manufacture especially soft and flexible electrode arrays permits MED-EL to design variants that allow a deep insertion into the cochlea while protecting the delicate inner ear structures. Electrode arrays specifically designed for deep insertion (Complete Cochlear Coverage) allow the stimulation of a maximum number of nerve fibers for a most natural hearing experience with the widest frequency (pitch) range possible (refer to the section on Complete Cochlear Coverage).
The PULSARCI100 and SONATATI100 implants offer a range of electrode options.*
Standard
Electrode Array
The Standard Electrode Array offers the deepest insertion
(approximately 31mm) and widest contact spacing (2.4mm)
available today. It features 12 pairs of electrode contacts
and is designed to provide stimulation of the complete frequency
range.
Medium Electrode Array The Medium Electrode
Array features 12 electrode pairs with moderate contact
spacing for cases where deep insertion is not desired or
is not possible due to anatomic restrictions.
Compressed Electrode
Array
Specifically designed for partial ossification or malformation
of the cochlea, the Compressed Electrode Array features
12 pairs of contacts equally spaced over a shorter distance
to maximize the number of channels available and optimize
performance.
Split
Electrode Array
Specifically designed for severe ossification of the cochlea,
the Split Electrode features two separate electrode branches,
one with five pairs and one with seven pairs of contacts.
The arrays are designed for insertion into different areas
of the cochlea to maximize the number of channels available
and optimize performance.
