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 the 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. A surgeon will decide which one is best for each of their individual patients' needs.

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

  • Most reliable cochlear implants over time.**,6
