Audiodent hearing aids, any release date?

Have you people heard of Audiodent?

Here’s some links^l1600&enPage=BlankPage&enDisplay=view&enDispWhat=object&enVersion=0&enZone=Technology&

It’s a new hearing aid that works with a transmiter that goes in your mouth, and receive vibrations from an external device, and transmits sound via the bones.
Similar to beethoven’s technique. Anyone knows anything about release date?
I read they already tested their prototype on almost all hearing losses and they received some nice feedback.

the idea sounds creepy…

how do you change your battery?

No idea, but I think the electronic part is the external device. It may work with a bluetooth technology, or something wireless. You wear the external thing and it will receive all the sound, and transmit it to the tooth device which will vibrate according to the sound to transmit it directly to the jawbone into the brain receptors.
