The piezo-electric or magneto-elastic element is arranged to be at least partially implanted in a surgically drilled hole directly into the mastoid bone behind the outer ear so that the vibrations are transferred directly from the element to the bone and transferred in the skull bone to the inner ear. The element is encapsulated with a bone integrating material, such as titanium or various biocompatible ceramic materials or coatings and is disc shaped and acts with a radial expansion upon electrical stimulation so that longitudinal sound waves are induced into the skull bone. | 07-15-2010 |
