FDA OK on SYNCHRONY cochlear implant

DURHAM, North Carolina – MED-EL USA officials announced that the U.S. Food and Drug Administration has approved the new SYNCHRONY cochlear implant. For the first time, a cochlear implant has been approved for use with 3.0 Tesla (T) MRI without the surgical removal of the internal magnet; it is the only implant available with this indication in the USA. SYNCHRONY will be available in spring 2015. 

“MED-EL has continued its unprecedented advancement in the area of cochlear implant and MRI safety,” said Raymond Gamble, president & CEO, MED-EL North America. “We are thrilled to be able to offer SYNCHRONY, which has revolutionized the cochlear implant landscape around the world, here in the United States.”

SYNCHRONY is compatible with all current MED-EL audio processors, including the recently approved SONNET. Like all MED-EL implants, it is designed to be future ready for the latest technology as it becomes available. It is the smallest and lightest titanium cochlear implant on the market, making it the ideal choice for even the youngest candidates.

Revolutionary magnet design
Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the body. During an MRI, SYNCHRONY’s magnet freely rotates and self-aligns within its titanium housing, greatly reducing implant torque and the risk of demagnetization during MRI scans. This design enables high-resolution 3.0T MRI scans without the need for magnet removal.  

The revolutionary conical design of the removable magnet housing greatly reduces the risk of magnet dislocation or migration. The implant features a polymer stiffening ring within the silicone implant body to further secure the magnet housing. Additionally, the magnet can only be removed from the bottom side of the implant, making dislocation of the magnet due to trauma almost impossible.

The implant is MR Conditional allowing MRI scans at 3.0T with the magnet in place. SYNCHRONY’s magnet housing can also be substituted with a non-magnetic spacer for MRI head scans with minimal image distortion in the implant area. The removable magnet housing features a protective coating to prevent unwanted cellular adhesion, simplifying the removal and replacement of the implant magnet. The incision for magnet exchange is made beside the implant, rather than directly over the implant, allowing uninterrupted hearing.

The SYNCHRONY PIN implant option also features titanium fixation pins proven to secure the placement of the implant for outstanding stability. SYNCHRONY incorporates MED-EL’s FLEX electrode arrays, which provide complete coverage of the cochlea for superior hearing performance and are engineered to preserve delicate cochlear structures for future advancements.
