When trying to choose a cochlear implant for my baby daughter, I spoke to someone at Cochlear and asked about fully implantable implants. There are actually several adults in Australia who already have them on a trial basis. The biggest problem they have been having--and it is big!--is that they can hear their own body sounds, which aside from probably being very disturbing means that they can't hear everything else as well as they can with an external processor. (They also have an external bit they can wear, and hear perfectly fine if that is on.) Also thus far the batteries would need to be changed too often, every five years I believe, which is a lot of surgery. The woman told me that it won't be available on the market until it is perfected, but they are working on it!
