With a diversity of sizes and shapes to choose from, your surgeon can find the electrode that best fits your cochlea’s natural curves. What’s more, our electrodes are crafted to help you distinguish more pitches, and experience sound in a more natural way.

MRI at your convenience

MRI scans are a standard medical diagnostic technique and Nucleus implants are designed to fit with your lifelong medical requirements. If you ever need a medium strength MRI up to 1.5 Tesla, you can rest assured that your Nucleus implant allows you to safely undergo the scan with your magnet in place*. And if you need a high-powered MRI up to 3 Tesla*, the removable magnet makes that possible in a simple outpatient procedure too.
