You Can Count On

Choosing a cochlear implant can be a decision for life—that’s why our cochlear implants are built to provide long-term safety and outstanding reliability. To ensure our candidates can make informed decisions, we provide honest, transparent, up-to-date reliability information on all of our current implants and audio processors.

We believe in putting the well-being of our recipients first, which is why we hold ourselves to one of the most rigorous reliability reporting standards. We follow ISO 5841-2: 2000, which is the reliability reporting standard for cardiac pacemakers and other life-saving devices.

We’re proud of the accomplishments of all our recipients, and we take responsibility for every single implant. Other manufacturers may disguise the replacement of a partial failure as an “upgrade”. We don’t believe that’s fair or honest to you. If an implant has to be removed or replaced for any reason, we count that against our reliability; you’ll find it reported below under “Extended CSR data”.

Comprehensive reporting is the fair and honest information that every cochlear implant candidate deserves. With MED-EL, you can trust you’ll have reliability you can always count on.
