An electroporation apparatus and the method of using same are provided. The apparatus allows for the ablation of an area of tissue of arbitrary volume. The apparatus includes a plurality of conductive electrodes attached to a base pate and electrically connected to a pulse generator to allow individual electrical actuation of the electrodes. In use, the electrodes are inserted into an area of tissue to be ablated, such that the electrodes are in a first position. Predetermined ones of the electrodes are then activated to ablate tissue surrounding the activated electrodes, while leaving other ones of the electrodes un-activated. The electrodes are then moved to a second position which is different than the first position, and predetermined ones of the electrodes are then activated to ablate tissue surrounding the activated electrodes, while leaving other ones of the electrodes un-activated.
