Cochlear's implant design philosophy
Designed to support a lifetime of hearing performance.*
Electrodes designed to fit the natural shape of the inner ear.1
Support advances in sound processor technology.
World's thinnest cochlear implants
The Nucleus® Profile™ and Profile Plus Series Implants are the thinnest in the world.**
Designed to fit the natural shape of your inner ear, sitting closer to the hearing nerve for better hearing outcomes.2-4
Both Profile Plus and 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 precise frequency coverage.
The world's thinnest full-length electrode.5
Electrodes which sit closer to the hearing nerve for better hearing performance.2-4
Best long-term implant reliability record in the industry.**6
