  • Stimulation rates up to 31.5 kHz
  • Enable the sound processor to confirm whether it is coupled to the nominated implant
  • Monopolar, bipolar & common ground stimulation modes using biphasic current pulses & flexible programming options
  • Telemetry capability - ultra low noise floor (~ 1 uV), enabling AutoNRT telemetry
  • Includes fully integrated electrophysiologic telemetry modes - NRT, Auto NRT, ESRT, ABR, CEP & intraoperative NRT
  • Access to 1.5T MRI with magnet in place
  • Access to 3.0T MRI with magnet removed
Cochlear Nucleus Profile with Slim Modiolar Electrode (CI532)



Cochlear Nucleus Profile Contour Advance CI512 features include:

The Nucleus Profile cochlear implant has a thin profile that is useful for cochlear implants for young children. The Nucleus Profile is available with a coiled electrode (Contour Advance CI512) and a Slim Straight electrode CI522 (see below).

  • Thinnest implant body with no pedestal
  • Indicated for both children and adults
  • Reinforced silicone rubber surrounding the implant for added protection
  • Titanium casing for high impact resistance
  • Implant coil enabling telemetry
  • Symmetric, side by side exit leads from main casing
  • Smooth external geometry to minimize biofilm formation and reduce risk of infection
  • Same device is used for the right or left ear
  • Removable magnet allows for MRI safety at 1.5 Tesla and reduced image distortion
  • Circle on magnet indicates the side that should be away from the bone
  • Sterilized replacement magnet (Z179608) and non-magnetic plug (Z146624) to assist MRI procedures
  • MRI compatible up to 1.5 Tesla with magnet removal.
  • Best MRI outcomes are achieved by removing the magnet which reduces image artifact by 60-70% around the implant site
  • Weight = 8.6 grams including electrode array
  • Impact = Resistant against external impact up to 2.5 joules

  • Intracochlear electrode, smooth lateral surface
  • Two white markers indicating insertion depth ranged at 20 mm and 25 mm.
  • Patented basal stiffener enabling a smooth, single motion insertion for ease of use and to minimize insertion trauma
  • Basal diameter at 0.6 mm
  • Handle and optimized lead angle for electrode orientation and ease of surgical handling
  • Two extracochlear electrodes designed to deliver a more individualized stimulation and better mapping
  • The slim straight electrode is suitable for round window or cochleostomy procedures
