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.

Abstract: A pulse generating device for delivery of electrical pulses to a desired tissue and configured to be connected to needle electrodes arranged at the desired tissue. The device comprises a determining module configured to determine a primary voltage amplitude of a first pulse and a number of consecutive pulses to be generated. Further, the device comprises a pulse generator configured to generate one or more of the determined number of consecutive pulses such that the generated first pulse has the primary voltage amplitude and that the generated consecutive pulses have a respective voltage amplitude consecutively decreasing between consecutive pulses, whereby an increase in a current value of the generated consecutive pulses above a threshold value is avoided. Furthermore, the device comprises a terminating module configured to terminate generation of the one or more pulses when a value of a total absorbed energy exceeds a threshold value.

Abstract: A device for delivery of electrical pulses to a desired tissue of a mammal. The device comprises a pulse generating device and an electrode device connected to the pulse generating device. The pulse generating device is configured to determine conductance and phase angle values between one electrode and a reference electrode of the electrode device when the electrode device is inserted into the desired tissue and when pulses based on alternating currents having different frequencies are generated between the electrode and the reference electrode. Based on the determined conductance and phase angle values, the pulse generating device is configured to determine the type of tissue the electrode device penetrates, to determine one or more parameters of electrical pulses to be delivered to the desired tissue and to generate the electrical pulses having the determined one or more parameters.
