Abstract
A prosthesis permits both an acoustic stimulation and an electrical stimulation of the inner ear and include an interposition element, one end of which is provided with a device for attachment to a downwardly extending branch of the anvil. The other end of the element is adapted to be applied on the oval window of the ear and has a conductive end surface constituting an electrode which is connected by a conductor covered with a biocompatible insulating covering to a source of electrical stimulation.
