Cochlear Nucleus implant system

The Nucleus system is Cochlear’s implant family under PMA P840024. The newest approval read is supplement S096 (decision July 3, 2025), which adds the CI1000 Series implants. This is a thin sheet: electrode and clinical specifications were not found in the sources read and stay Unreported. MED-EL and Advanced Bionics are separate families.
