Abstract: A method of identifying upon insertion into soft tissue a microelectrode of a set of three or more microelectrodes each comprising an electrically conductive body comprises providing the microelectrode with a unique metallic pattern of three or more sections separated from each other and disposed in an axial direction on the body and/or on one or more insulating layers on the body; inserting the microelectrode into the tissue simultaneously or consecutively with the other microelectrodes of the set; detecting the pattern by computer tomography (CT) or X-ray. Also disclosed are microelectrodes provided with unique patterns and sets of such microelectrodes and their use.

Abstract: A microelectrode comprises an oblong electrically conducting electrode body covered by distal and proximal sections of a layer of insulating material except for an annular contact section disposed between them, a blunt distal bulge at the distal end of a radial extension substantially greater than that of the proximal section of non-conducting material. For implantation into soft tissue the microelectrode is provided with a support of a material dissolvable in body fluid. Also disclosed is a set of microelectrodes sharing such support, a method of manufacture of the microelectrode and the set, and uses of the microelectrode and the set.
