Abstract: A combined set including a vibration actuator and an implantable device provided to be implanted in an inner ear part is disclosed. The implantable device has a surface in contact with an inner ear fluid when inserted in said inner ear part. The implantable device includes a frame having an inner wall and a slidably movable member having an outer wall which is connected to the vibration actuator. The slidably movable member is provided for transferring energy supplied by the vibration actuator from and towards the inner ear fluid by means of a translational movement. The slidably movable member is at least partially mounted inside the frame in such a manner that a gap extending between the inner wall of the frame and the outer wall of the member is less than or equal to 0.1 mm.

Abstract: A combined set (71) comprising a vibration actuator and an implantable device to be used as an artificial fenestrum implantable in a bony wall (25) of an inner ear, said device comprising a frame (32) made of a bio-compatible material and provided to be applied at least partially in said bony wall, said frame being provided with a wall part formed by a membrane (27) forming a barrier with a perilymph of said inner ear when applied in said bony wall, said membrane being provided to form together with said frame an interface with said inner ear, said interface being provided for energy transfer towards and from said inner ear, said membrane being electrically dissociated from said vibration actuator and provided for receiving vibration energy from said vibration actuator.

Abstract: An auditive prosthesis, including a cochlear implantable electrode-set applied on a carrier. The electrode-set provides electrical currents for stimulating auditory nerves in the modiolus. The electrode-set having a first series of electrode-poles arranged beside each other and at a predetermined distance of each other along a first longitudinal side of the carrier. Each of the electrode-poles of the first set are individually connected with a signal-generator. The signal-generator is a second electrode-pole connected with a signal-generator. The second electrode-pole is arranged along a second longitudinal side of the carrier and extending over substantially the same distance as the first electrode-poles. The signal-generator is provided for generating signals between selected electrode-poles, electrical field-lines with radial and/or longitudinal components.
