Perimodiolar means better hearing performance1, 2, 3, 4

For sixteen years, Cochlear has offered perimodiolar electrodes because of:

  • Atraumatic stimulation of the ‘hearing zone’ 5, 6, 7, 8, 9
  • Precise stimulation 10, 11, 12, 13, 14, 15, 16, 17, 18, 19
  • Near zero insertion forces 20

The ‘ideal’ electrode has to be as atraumatic as possible, capable of retaining residual hearing and also be able to preserve the delicate structure of the inner ear.

It has to be as close as possible to the modiolus to deliver precise stimulation, adapt to the length of the cochlea and be as thin as possible.

Following independent studies and surgeon recommendations, we have designed an electrode that makes a difference for patients.

Deliver optimal hearing outcomes for patients with an electrode that sits closest to the hearing nerve

The Slim Modiolar Electrode is built on the industry-leading hearing performance of the Contour Advance®, with even closer perimodiolar positioning and consistent scala tympani placement to deliver an optimal hearing performance.

  • Closest to the hearing nerve 21
  • Consistent and complete scala tympani placement 22
  • Optimal hearing outcomes 23

This electrode allows the stimulation point to get close to the target neurons in the cochlea with less trauma to the structure of the cochlea.

In a multicentre study, 100% of slim modiolar electrodes were successfully placed in the scala tympani. 23

Protect and preserve the delicate inner ear with the world's thinnest full-length electrode

Maximising hearing performance depends on minimising insertion trauma24. Cochlear’s largest ever temporal bone study has shown that the Slim Modiolar Electrode preserves the delicate structures of the inner ear, with no intracochlear trauma apparent in 98% of the specimens. 25, 26

I would like to offer patients all the advantages of a perimodiolar electrode, combined with a slim, atraumatic electrode.

Select your surgical approach with this reloadable electrode which is smooth and easy to insert.

The Slim Modiolar Electrode features a unique insertion mechanism, allowing surgeons to select the most appropriate approach depending on the cochlea anatomy. For peace of mind, the electrode can be reloaded if required.

The reloadable design will increase the surgeon's ability to place the electrode in an optimal position.
