Study Shows that Improved Cochlear Implant Device Allows Safe MRI in Children without Discomfort


A study from Ann Robert H. Lurie Children’s Hospital of Chicago found that children with a MED-EL SYNCHRONY cochlear implant device can undergo MRI safely, with no discomfort and reduced need for sedation or anesthesia. Findings were published in the peer-reviewed journal Laryngoscope.

The study only included subjects with the MED-EL SYNCHRONY implant, which has a rotating magnet that aligns with the MRI magnetic field.  The HiRes Ultra 3D implant from Advanced Bionics has magnets that rotate in multiple axes, so the head can be in any orientation.  The Nucleus 7 implant from Cochlear has a rotating magnet for MRI compatibility as well.

Cochlear Announces MRI-Safe Implant

Cochlear announces the launch of the Nucleus® Profile Plus Series implant, designed for routine 1.5 and 3 Tesla magnetic resonance imaging scans without the need to remove the internal magnet.

Initial availability is in Germany, appearing in other markets pending regulatory approval.

With this announcement, all three major cochlear implant manufacturers offer up to 3T MRI compatibility without removal of the internal magnet.  More information on the differences between options will be forthcoming.

Cochlear Receives FDA Approval for MRI on Several Implants

mri-magnetom-skyra-mediaviewer_10-00092827-10The US FDA Approves many Cochlear (brand) implants for 1.5T MRI with magnet in place with the use of the Cochlear Nucleus Implant Bandage and Splint Kit, and for 3.0T MRI with magnet removed.

The following Nucleus Profile and Freedom implants are covered with this approval:

• Nucleus Profile: CI512, CI522, CI532
• Nucleus CI24RE: CI422, CI24REH, CI24RE(CA), and CI24RE(ST)

*Does not apply to CI24R, CI24M, CI22M

Advanced Bionics Receives CE Mark Approval of Expanded MRI Compatibility for Cochlear Implants

— HiRes 90K and HiRes 90K Advantage cochlear implants allow 1.5T MRI scans with the CI magnet in place —

Valencia, Calif., February 3, 2015— Advanced Bionics (AB), a global leader in cochlear implant technology and a company of the Sonova Group, announced today that the HiRes 90K™ and HiRes 90K™ Advantage cochlear implants have received CE Mark approval from the European Notified Body, TÜV, to undergo 1.5T MRI scans without removing the internal magnet. Previously, these devices had regulatory approval to undergo MRI scans only if the magnet was removed.

Magnetic Resonance Imaging (MRI) is an increasingly common tool for diagnosing conditions such as cancer and heart disease. This additional compatibility for MRI scans while the CI magnet remains in place helps simplify the diagnostic process by avoiding additional pre- and post-MRI procedures to remove and then to replace the magnet. “Advanced Bionics prioritizes the safety and well-being of patients with our cochlear implants. We are very pleased to offer patients this additional compatibility with MRI diagnostic equipment,” said Hansjuerg Emch, Group Vice President Medical of the Sonova Group.

Cochlear implants are implanted just beneath the skin, and use magnets to link the internal and external components of the CI system. The internal component of the AB cochlear implant system includes electronics and an electrode array that deliver AB’s proprietary current steering technology for hearing that more closely resembles normal hearing. The newest AB electrode array, the HiFocus™ Mid-Scalaelectrode, was designed for optimal placement in the cochlea with low insertion force to protect its delicate structures. The HiFocus Mid-Scala electrode accommodates the latest soft surgery approaches, including round window insertion, to suit surgeon preferences and individual recipient needs. The patented design allows for ideal placement so recipients have the opportunity to hear the most pitches possible for enjoying music and improved speech understanding.

The external component of the AB cochlear implant system includes a sound processor that sends signals via the headpiece to the internal component. Partnering with Phonak, the world leader in hearing instruments, AB brings its innovative, industry-leading technology to help people with significant hearing loss for whom hearing aids are no longer sufficient. The combination of AB and Phonak technologies makes the Naída CI the most advanced sound processor available, offering high-performance hearing in all environments, 100% wireless connectivity to consumer electronics, bimodal capabilities that allow streaming to the processor and a compatible Phonak hearing aid at the same time.
