The invention relates to a hearing prosthesis comprising an inner ear implant (10) that has a carrier structure (11) and at least two electrodes (12) arranged at a distance from each other in the longitudinal direction. Said electrodes can be activated individually and are connected to the carrier structure (11). The carrier structure (11) can be compressed and expanded in a stent-like manner in such a way that it (11) can be adapted to the shape of the inner ear. The invention also relates to a method for producing such a hearing prosthesis.
