World's thinnest implant: Cochlear™ Nucleus® Profile™ Implant
The Nucleus Profile and Profile Plus Series implants are the thinnest in the world.*
They are designed with a flexible coil to better fit the natural shape of your head.
Profile Series implants also have a high impact resistance — up to 2.5 joules — which meets the European standards for impact testing.
Industry-leading design for hearing performance
The anatomy of the cochlea varies from person to person. That's why we offer a range of electrode shapes and lengths. Your surgeon will decide which one is best for you.
Unique features of Cochlear's electrodes and implants include:
22 active contacts for maximum frequency coverage along the hearing nerve.
The world's thinnest full-length electrode.
The Hybrid™ L24 Electrode+ that is specifically designed and approved to preserve hearing.
Electrodes which sit closest to the hearing nerve for your best hearing performance.1,2
Best long-term implant reliability record in the industry.*3
Electrode placement critical to hearing performance
Surgeons place Cochlear's electrodes where hearing nerve stimulation is most effective and where they expect that you may benefit from the full range of sound.
This area is known as the hearing zone. It is the area closest to the hearing nerve, the target of electrical stimulation.4
Clinical research shows that inserting an electrode beyond the hearing zone is associated with deterioration in performance. It can also damage the delicate cochlear structures.4,5
Correct insertion depth — along with the highest number of active contacts in the industry (22 electrodes) — help to give you the full spectrum of sound and a richer hearing experience.
Built for MRI compatibility
We designed the Nucleus Profile™ Plus Series Implant so you can have a routine 1.5 T MRI or high-definition 3.0 T MRI without removing its magnet**. This means no additional surgery, no need to wear a bandage in the MRI machine, no waiting for your scan and, most importantly, no unnecessary time without sound.
Because we were the first manufacturer to introduce removable magnets, more Cochlear recipients have MRI-compatible implants than any other cochlear implant brand. Even a person implanted many years ago can access today’s MRI technology***.
