The Med-EL cochlear implant system is called the SYNCHRONY System and combines a number of powerful technologies. Med-EL has introduced the concept of "Triformance" in an attempt to provide patients with a natural sense of hearing given our available technology.

Triformance combines the design concepts of:

  • Complete cochlear coverage - full-length, long electrodes to cover the entire length of the cochlea
  • FineHearing - a sound coding strategy that delivers the deepest bass tones available
  • Structure preservation - electrodes designed to be soft, gentle, and flexible to protect remaining, delicate cochlear structures

Components include:

  • Synchrony Cochlear Implant ( surgically implanted electronics)
  • Sonnet Audio Processor (ear level processor that magnetically links with the Synchrony CI)
  • Optional Rondo Single-Unit Processor (processor that magnetically links with the Synchrony CI)
  • Maestro System Software (current version 6.0) & MAX Programming Interface for programming the Synchrony CI
    • Bilateral, single unit design
    • Switch-less design that works with a computer interface
    • Maestro will permit programming the Synchrony with 4 specific maps for different listening environments
    • Data-logging for Sonnet processor that includes usage time and volume range
    • Supports all currently available Med-EL CI's and audio processors

SYNCHRONY Cochlear Implant

The Synchrony CI by Med-EL is available in multiple electrode configurations.

Features include:

  • Conditionally MRI safe at 1.5 and 3.0 Tesla strength without the need for magnet removal
  • Rotatable, self-aligning magnet that reduces torque for increased patient comfort during MRI scans
  • CI design that permits magnet removal, if necessary, to minimize MRI image distortion (requires special instruments for removal)
  • Magnet is removed from the medial side of the implant making dislocation due to trauma almost impossible
  • Designed with Synchrony PINs consisting of titanium fixation pins to help secure the placement of the implant to enhance stability and help prevent inadvertent implant migration.
  • Smallest titanium CI available, especially nice for pediatric patients

Med-EL cochlear implant design provides a comprehensive electrode portfolio to permit customization of electrode length and shape to accommodate differences in individual cochlear anatomy:

  • Two electrode designs: CLASSIC Series and FLEX Series
  • Featuring atraumatic electrodes in various lengths and shapes
  • FLEX series electrodes are engineered to help ensure cochlear integrity and atraumatic insertions
  • Unique FLEX-Tip technology featuring:
    • Single contacts at the leading end
    • Full length tapered tip design
    • Ultra-flexible, wave-shaped wires
    • Tapered tip for increased mechanical flexibility
