Title
(EN) FLEXIBLE CIRCUIT ELECTRODE ARRAY WITH AT LEAST ONE TACK OPENING
(FR) MATRICE D'ÉLECTRODES POUR CIRCUIT FLEXIBLE AVEC AU MOINS UNE OUVERTURE DE POINT DE SOUDURE
Abstract
(EN)
The present invention provides a flexible circuit electrode array adapted for neural stimulation, comprising: a polymer base layer; metal traces deposited on said polymer base layer, including electrodes suitable to stimulate neural tissue; a polymer top layer deposited on said polymer base layer and said metal traces at least one tack opening; wherein said polymer base layer, said metal traces and said polymer top layer are thermoformed in a three dimensional shape. The present invention provides further a method of making a flexible circuit electrode array comprising depositing a polymer base layer; depositing metal on said polymer base layer; patterning said metal to form metal traces; depositing a polymer top layer on said polymer base layer and said metal traces; preparing at least one tack opening; and heating said flexible circuit electrode array in a mold to form a three dimensional shape in said flexible circuit electrode array.
