Implanted hearing prosthesis

摘要

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.
