Products Liability Firm Handling Claims Nationwide & Internationally
Shoop | A Professional Law Corporation is now handling multiple cases involving
the Cochlear Nucleus CI512 recall. On September 16, 2011, Cochlear Ltd.,
the device manufacturer, issued a product recall on the Nucleus CI500
range in conjunction with the FDA. Accounting for approximately 28,000
users, this device was on the market as early as 2009 and is now experiencing
multiple, post-implant failures. The company maintains that it is still
"investigating the cause of these failures." With that said,
the Nucleus CI 500 line accounted for approximately 70% of Cochlear sales in 2011.
Why Was There A Recall?
An internal investigation revealed that these cochlear implant failures
were causally related to "unexpected variations in the brazing process"
during implant manufacturing. These manufacturing defects caused the development
of "microcracks" affecting the structural integrity of the N5
devices which, in turn, allow water to penetrate the devices. As a result,
the implants failed to achieve a hermetic seal, thereby allowing moisture
and saline from the inner ear where the implant is situated to penetrate
the device. This moisture inside the unit then short-circuits the diodes
which power the device, causing the devices to shut down. Numerous recipients
of these failed devices have experienced both vestibular issues as well
as painful shocking sensations as the device fails.
Proving Liability For A Defective Product
In July of 2011, just two (2) months before Cochlear, Ltd., issued a voluntary
recall for the Nucleus CI500 range of cochlear implants, Cochlear Ltd.,
notified physicians in a Clinical Product Update that the ground electrodes
in some Nucleus CI512 implants (claimed to be less than 0.3%) had open circuits.
This product defect means that while the Nucleus has two electrodes, one
of the electrodes was failing. Cochlear assured physicians that the primary
purpose of having two electrodes was for redundancy, and that if the Monopolar
2 (MP2) ground electrode failed, that the default mode of stimulation
for mapping would become Monopolar 1(MP1).
Cochlear also acknowledged that the intended stimulation mode for mapping
was a combination of both electrodes MP1+MP2. Cochlear Ltd. indicated
that a patient's hearing performance would not be affected if the
MP2 ground electrode failed because of an open circuit. Cochlear Ltd.,
also stated that if a surgeon implanting the device identified through
impedance testing that the MP2 electrode was open, that the surgeon should
decide whether to use a different device.
However, Cochlear Ltd. did not state that the Nucleus CI512 was defective
in manufacture or design. Instead, Cochlear Ltd. represented that it had
identified the mechanism causing the open circuit in the MP2 ground electrode,
and that it was putting in place processes to correct the defect. With
regard to the use of the Nucleus CI500 Range, Cochlear stated that it
would always support the surgeon's decision on whether to use the
device. Moreover, Cochlear Ltd., Chief Executive, Chris Roberts, advised
that the company was in no rush to conclude an investigation into the
cause of these multiple, device failures, which reportedly relates to
moisture in the devices that can cause a malfunction in one or more diodes.
"Advice to clinics suggests that analysis of the moisture indicates
that it is not related to body fluid," UBS analyst Andrew Goodall
said. If this is indeed the cause, this would implicate an obvious flaw
in the manufacturing process for which Cochlear Ltd. is strictly liable in tort.
What You Should Do If You've Recieved a Nucleus CI512
Cochlear Americas is sending letters to users of the device and the parents
of minors who have a Nucleus CI512 that has failed, offering to work with
the patient's insurance company to replace what would appear to be
defective in both design and manufacture. Shoop | A Professional Law Corporation
recommends that patients and parents of minors not release any of their
rights to recovery for injuries sustained and financial losses, without
first consulting an attorney who has substantial experience in the investigation of
defective products, and litigating cases involving defective medical devices.
During the course of our investigation and handling of these Cochlear N5
claims, we have discovered that numerous recipients of these failed devices
have experienced both vestibular issues as well as painful shocking sensations
as the device fails. We can help you.If you or a family member has suffered
a failure of this divise.
