摘要

electrode carrier guide, especially for cochlear implants, cochlear implant provided with said guide, and method for manufacturing electrode carrier guides.; The guide is elongated and substantially flat, and has a plurality of electrodes (2), connected to corresponding contacts (3) via tracks (4); It comprises at least two overlapping basic cells (CB1, CB2, ... CB11), each with a base layer (11) insulation on which is arranged a layer (12) forming conductive electrodes (2), the tracks (4) and contacts (3).; The method comprises superimposing successive insulating and conductive layers and defining suitable by photolithography to form electrodes, contacts, tracks and windows for accessing the electrodes and contacts geometries.; The invention allows automated manufacture of a guide with a large number of electrodes and suitable for atraumatic implantation externally to the scala tympani dimensions.
