Cochlear’s Implant design philosophy
All our implants are designed to last a lifetime with performance and preservation of the cochlear structures in mind.* Our broad range of implants and electrodes allow your surgeon to choose the best one for your or your child's type of hearing loss, cochlea anatomy and the surgeon's preference. In addition, we design our implants with the future in mind by allowing for future advances in sound processor technology without the need for additional surgeries.
“I chose Cochlear because they have a very strong track record for making the newer technologies available to prior generation implants.”
- Oscar H. - Father of Nucleus® recipient
World’s thinnest implant—Cochlear Nucleus Profile Implant
The Nucleus Profile Series implant expands our large implant portfolio by providing the thinnest implant available.1-3 Its thin size and design follows the curvature of the head for the potential of a better cosmetic outcome and less time in surgery. Profile Implant also has a high impact resistance—up to 2.5 joules—which meets the European standards for impact testing.
Industry-leading innovations in electrode design for optimal hearing performance
The anatomy of the cochlea can vary from person to person which is why we offer a range of electrode shapes and lengths. Your surgeon will decide on the best one to provide your best hearing performance. Unique features of Cochlear's electrode portfolio include:
- 22 active contacts** for maximum frequency coverage along the hearing nerve
- The Hybrid L24 Electrode+ that is specifically designed and approved to preserve hearing
- Perimodiolar electrodes that are inserted closest to the hearing nerve for your best hearing performance4,5
- Best long-term implant reliability record in the industry6-8
- Easy to remove magnet to ensure safety and comfort for MRIs
Electrode placement is critical to hearing performance
Cochlear's electrodes are placed where hearing nerve stimulation is most effective. In order to benefit from the full range of sound, the area closest to the hearing nerve tends to be stimulated.10-11 This area is known as the hearing zone.
Clinical research shows that deeper insertion beyond the hearing zone can be associated with deterioration in performance due to pitch confusion at the tip of the cochlea as well as damage to the delicate cochlear structures.11-12 Insertion depth along with the most active sequential contacts in the industry—22 electrodes**—help provide access to the full spectrum of sound and a richer hearing experience.
