What These Implants Do
Cochlear implants restore hearing by electrically stimulating the auditory nerve. They’re surgically implanted devices designed to function inside the body for years, providing consistent auditory sensation to people with severe hearing loss.
The Shutdown Problem
According to FDA records, these CI512 implants could shut down and cease to function. Not gradually degrade, not require adjustment—just stop working entirely.
Already Inside People’s Bodies
When the recall was announced in September 2011, more than 25,000 of these implants had already been surgically placed. Another 1,741 remained in the U.S. market waiting to be implanted in patients.
The October 2011 FDA Classification
The FDA classified this as a Class 2 recall on October 3, 2011, after Cochlear Americas initiated the recall on September 16, 2011. Class 2 means the device could cause temporary or reversible adverse health consequences.
33,645 Units in Commerce
The recall affected 33,645 units distributed worldwide, including the United States, Europe, and Australia. This wasn’t a small batch problem—it was a global distribution of potentially defective implants.
Component Design Issue
The FDA identified the cause as a “component design/selection issue.” In plain language, someone chose or designed a component that wasn’t reliable enough for a device meant to function inside the human body for years.
What Happens When an Implant Fails
If your cochlear implant shuts down, you lose the hearing benefit it was providing. For children developing language skills or adults who’ve regained their ability to hear, that sudden loss can be devastating.
The Revision Surgery Question
When an implanted device fails, the solution often requires another surgery to remove the defective implant and replace it with a working one. That means going through the entire surgical process again, with all the associated risks, recovery time, and costs.
Part Number Z209051
The recall covered all codes for part number Z209051. If you’re trying to determine whether you have a recalled implant, check your implant records, operative reports, or device identification card.
Made in Australia
These implants were manufactured in Australia and distributed globally. The FDA database lists them as sterile implants intended for electrical stimulation of the auditory nerve.
The September 16 Letter
Cochlear Americas sent urgent medical device recall letters to affected customers on September 16, 2011. The notice instructed facilities to examine inventory, quarantine affected products, and return response forms.
What About Patients?
For clinics, quarantining inventory is straightforward. But for the 25,516 people with these implants already inside their bodies, the “remedy” wasn’t so simple—you can’t quarantine an implant that’s been surgically placed.
Living With Uncertainty
After the recall announcement, every patient with a CI512 implant had to live with the knowledge that their device could shut down at any time. That’s not a minor concern when you’re relying on the device for basic communication and quality of life.
Language Development Impact
For children with cochlear implants, consistent auditory input is critical for language development. A device that could randomly shut down threatens that developmental process.
Communication Disruption
Adults who regained hearing through these implants built their lives around being able to communicate verbally. Sudden device failure doesn’t just take away sound—it disrupts work, relationships, and daily independence.
The Emotional Toll
Beyond the medical and functional impacts, living with a device you know could fail creates constant stress and anxiety. Every moment of unexpected silence makes you wonder if your implant just shut down.
Medical Records Are Key
If you’re considering legal action, gather your operative reports, implant records, device identification cards, audiology records, and any correspondence from Cochlear or your implanting clinic. Product identification for implanted devices comes from medical files, not retail packaging.
Breach of Reliability Standards
Medical devices surgically implanted in the body must meet extraordinarily high reliability standards. A component design issue that causes devices to shut down violates the basic expectation that these implants will function consistently over their intended lifespan.
Contact an Attorney
If you received a Cochlear Nucleus CI512 implant and later experienced device shutdown, failure, loss of hearing benefit, or needed revision surgery, contact a product liability attorney. Preserve all medical records documenting the implant, any failures or problems, revision procedures, and the impact on your hearing and quality of life.
