We have no idea when we'll be eligible for the upgrade (no additional surgery is needed), but I am completely obsessed with Cochlear's NEW implant system, the Nucleus 5.
It has increased water resistance, which is my number one gripe concerning Christian's current CI (also made by Cochlear). It looks smaller, sleeker, and it has a lot of flexibility. I hope that the upgrade information is released soon so we can start to budget!
If you're going to be implanted with the Nucleus 5, or if you have a little one who will be, please keep me posted!
