Internal component cochlear implant Nucleus® Nexa®

pediatric

Product overview
The Nucleus® Nexa® Implant is a cochlear implant designed to store a recipient's individualized hearing configuration on the implant and to support firmware-based feature updates. It enables transfer of settings to new Nucleus Nexa sound processors and prepares the implant for future software improvements.

What makes it smart
The implant integrates onboard memory and upgradeable firmware to retain personalised program information and to allow software-delivered enhancements over time, reducing the need for manual reprogramming after processor replacement.

Key features

• Onboard memory: securely stores individual hearing configuration and program data on the implant.
• Upgradeable implant firmware: provides access to new or improved software features as they become available.
• Compatibility with the Nucleus Nexa sound processors, designed to optimise comfort and power efficiency.
• Adaptive power management in the Nexa system to maximise sound processor battery life.

Designed for better hearing
Surgeons can choose among electrode options to match cochlear anatomy and clinical requirements. Electrode selection enables tailored therapy intended to optimise hearing outcomes for each recipient.

Electrode and performance details

• 22 active contacts for comprehensive frequency coverage.
• World's thinnest full-length electrode to reduce bulk and support less invasive placement.
• Electrode designs positioned closer to the auditory nerve to improve stimulation specificity and performance.

MRI safety and compatibility
The Nucleus Nexa Implant is MRI conditional and supports routine 1.5 T MRI and high-definition 3 T MRI without magnet removal, minimising interruptions to hearing access during imaging procedures.

Experience and reliability
Since 1981 Cochlear has provided more than 750,000 implantable devices globally. The Nucleus Nexa Implant builds on this clinical experience and is engineered for long-term performance and discreet implantation.
