Abstract: The invention relates to an electrode-bearing guide, a cochlear implant comprising said guide and the production method thereof. According to the invention, the long and essentially flat guide comprises a plurality of electrodes (2) which are connected to corresponding contacts (3) by means of tracks (4). The inventive guide also comprises at least two stacked basic cells (CB1, CB2, . . . CB11), each of said cells comprising an insulating base layer (11). Moreover, a conductive layer (12) is disposed on top of the aforementioned insulating layer and forms the electrodes (2), the tracks (4) and the contacts (3). The production method consists in successively stacking insulating and conductive layers and defining suitable shapes by means of photolithography in order to form electrodes, contacts, tracks and windows for accessing the electrodes and contacts.

Abstract: Support or micromanipulator (100) for a surgical tool (20) comprising a complaint mechanism (1) providing direct support to the surgical tool (200), a positioning mechanism giving support to said complaint mechanism, and an attachment mechanism giving support to said positioning mechanism. The complaint mechanism (1) is made of a complaint material and allows three or four degrees of freedom to the movement of the tool (200). The positioning mechanism is located between the attachment mechanism and the complaint mechanism (1) and allows positioning of the same with six degrees of freedom. The attachment mechanism fastens the assembly to a surface of the surgical intervention region. The micromanipulator (100) is especially useful for practicing surgical interventions in the cochlea (performing cochlear implants, obtaining samples, etc), or other interventions for which high precision with the tool (200) is required.
