Electrode Arrays


Flexible and Atraumatic

MED-EL Electrodes Feature Wave-Shaped
Wires for Maximum Atraumaticity

MED‑EL electrode arrays are designed to preserve the delicate structures of the inner ear. The electrode arrays feature ultra-flexible wave-shaped platinum-iridium wires. The wave-shaped wire design is the key to making MED‑EL electrode arrays the world’s most flexible and atraumatic.

Minimising trauma during electrode insertion maximises the benefit to the patient. The wave-shaped wires reduce rigidity by half as compared to a straight-wire design.1 Benefits include the preservation of residual hearing as well as of the integrity of intraneural tissue targeted for electrical stimulation.

MED‑EL offers several different electrode array options, each featuring atraumatic wave-shaped wires. As a result, each implant recipient can be sure to receive the best possible electrode array for his or her unique hearing solution.
