The product liability lawyers at Shoop | A Professional Law Corporation continue to investigate and take on additional matters involving the Advanced Bionics HiRes90k cochlear implant. Although the initial product recall was undertaken several years ago, these cochlear implants continue to fail, post-implant. If you are an Advanced Bionics HiRes90k recipient and your device is exhibiting intermittent functionality or other signs of failure, it is very important to contact the product liability lawyers at Shoop | A Professional Law Corporation as soon as possible for a free of cost case evaluation and to further discuss next steps. No other law firm in the nation represents more victims of failed cochlear implants than we do. Let us put our experience and knowledge of this device to work for you in the event of an implant failure.


In our long history and experience representing clients across the country in claims involving failed cochlear implants, one of the first questions we are asked is, “how do I know if my implant has failed?” Often times there are periods of frustrating intermittency wherein the implant stops working for extended periods of time but has not yet completely shut down. Although cochlear implant manufacturers include in their recall notices that the devices “safely shut down” when they ultimately cease to function, many of our clients have told us that they hear high-pitched sounds, whistles and/or experience painful shocking sensations from the device.

If any intermittent functionality occurs, it is a good first step to alert your audiologist and personal physician. They can then coordinate and schedule appointments with on-call audiologists from the respective cochlear manufacturers and administer an Integrity Test Report to determine conclusively if the device has failed. Often times, the failure of these cochlear implants results from the device’s inability to achieve a hermetic seal, thus allowing moisture to enter the implant and shut down the diodes which power them.


You may have received a letter from Advanced Bionics notifying you that the implant you or a loved one received contains a component called a feed-thru device which was manufactured by a "Vendor B" (an unapproved, device-component supplier). The components manufactured by this supplier have failed at an alarming rate due to excess moisture, amongst other issues in our experience with this component, some feed-thrus have separated entirely from the unit, causing catastrophic failure.

If you are an Advanced Bionics HiRes90k Vendor B recipient, do NOT sign a release with Advanced Bionics in exchange for nominal reimbursement. This could potentially affect your legal rights to recover additional sums in a lawsuit or settlement with the company.

If you or a loved one suffered a failure of a HiRes90k implant, it is very important to contact our legal team immediately so that we may provide a FREE of cost case evaluation and initial discussion of your potential case.
