Abstract
A bio-probe having a base and a tip, and comprising a longitudinal core of substantially rigid material. On the core, there is a first layer of dielectric material, supported by and substantially circumferentially surrounding the core. Also, a set of conductors, each conductor extending longitudinally along the first layer of dielectric material and a second layer of dielectric material, substantially covering each of the set of conductors. For each of the conductors, an aperture is defined through the second layer of dielectric material to the conductor, thereby defining an electrode. In one preferred embodiment of this aspect, the first layer of insulative material is in the form of a tube and wherein the core is removable from the tube.
