Abstract

An electrode device for use in delivery of electrical pulses to a desired tissue of a mammal. The electrode device comprises a handle portion comprising first second electrode connections, and first and second needle electrodes comprising a respective first and second attachment end. Each one of the first and second electrode connections is configured with an inner electrode position and an outer electrode position, wherein the inner and outer electrode positions are electrically conducting. Further, each one of the first and second attachment ends is configured with an insulating part configured to electrically insulate one out of the inner electrode position and the outer electrode position when located therein, and configured with an electrically conducting part configured to conduct current supplied to the other one out of the inner electrode position or the outer electrode position when located therein.
