The present invention provides a probe device (20) comprising a substrate (25) and a die (23) on top of the substrate (25), the die (23) comprising an array of stimulation/recording sites (21) having at least one stimulation means and at least one recording means. The substrate (25) comprising the die is folded into a cylindrical shape or a shape with a conical cross-section and therefore causes substantially no damage when it is implanted in tissue to be examined or treated, e.g. the brain of a patient in case of a neuro-probe device (20) for use in DBS.
