Reliability You Can Trust

With implant reliability, it can be hard to understand what all the technical information means. You are making a once-in-a-lifetime decision and you deserve accurate information.

At MED-EL, we have always been committed to honest and transparent reliability reporting. If one of our implants has to be removed or replaced for any reason, we count that against our reliability. You will find our complete and transparent reliability data reported below. This comprehensive reporting is the fair and honest information that you deserve.

Made in Europe

For almost 30 years, we have proudly made all MED-EL cochlear implants right here at our headquarters in Innsbruck, Austria. We use state-of-the-art manufacturing facilities, cutting-edge processes, superior components, and exceptional quality control. This ensures every MED-EL cochlear implant can meet the highest standards of quality and reliability.

We believe this focused oversight and expert craftsmanship is essential for quality. That is why, unlike other companies, MED-EL does not outsource its implant manufacturing overseas.

Safety Capacitors

Safety Capacitors

When it comes to making truly reliable cochlear implants, it’s what’s on the inside that counts. One of the most important safety and reliability mechanisms in MED-EL cochlear implants are independent safety capacitors for every electrode channel. These safety capacitors act as a safeguard to help ensure the implant stimulation is always precisely controlled.

In fact, they’re so important, we dedicate almost half the space inside our cochlear implants to safety capacitors. There’s 14 capacitors total; one for each independent electrode channel, plus two more for the reference electrodes. With independent safety capacitors protecting every channel, our implants can safely run much faster and longer stimulation, and deliver more advanced sound coding.

This incredibly advanced hardware is also what makes MED-EL cochlear implants ready for the future. With precision safety capacitors on each independent electrode channel, there’s so much potential ready to be unlocked by future innovations in sound coding technology.

Complete Reliability

Our cochlear implants are made for a lifetime of hearing—which means we are thinking about where you will be 5, 10, and 20 years from now. Looking to the future, we know everyone will likely need to have MRI scans, because MRI scans are becoming more and more common.

That is why we created the first cochlear implant that offers superior safety, comfort, and security during 1.5 & 3.0 Tesla MRI scans. Other implants may require surgery to remove the magnet of the implant before an MRI, or risk pain, discomfort, or damage to the implant, which then becomes a reliability issue.1,2,3

With our SYNCHRONY Cochlear Implant, there is no surgery, no discomfort, and no hearing downtime. With MED-EL, you will have peace of mind knowing you are ready for anything life brings.

Made for Everyday Life

We do not just make truly reliable cochlear implants—we also design all of our audio processors to deliver outstanding reliablity.4

Our audio processors are designed to be exceptionally reliable. The average monthly service rate shows that less than 1% of our audio processors are sent to us with issues that require service.4

Why is that so important? A reliable audio processor means reliable hearing in everyday life—saving you time, money, and hassle. You will be taking your audio processor everywhere you go, so make sure it is one you can rely on.

A Lifetime of Hearing

From the very beginning through today, MED-EL has been guided by our founders, the inventors of the modern micro-electronic multichannel cochlear implant. Our mission is to overcoming hearing loss as a barrier to communication and quality of life.

To us, reliability is not a percentage on an earnings report for investors. Every recipient is a person, not a number. When you choose MED-EL, we understand you are putting your trust in our hands, so we make sure we are always there for you.

These figures represent the percentage of recipients in the study who experienced discomfort, pain, or other complications during 1.5 T MRI (two 3.0 T scans were excluded from the figure). Kim et al. (2015) is a retrospective study looking at 1.5 T and 3.0 T MRI scans performed on CI recipients between 2003 and 2014. The study included 18 individuals; 5 recipients had Advanced Bionics devices, 11 had Cochlear devices, and 3 had MED-EL implants. Advanced Bionics recipients had 9 total 1.5 T scans; Cochlear recipients had 12 total 1.5 T scans and 2 total 3.0 T scans; and MED-EL recipients had 8 total 1.5 T scans.
