Abstract:
An electrode apparatus for the application of electric fields to a selected portion of a living body, comprising;a support member; an array of at least two pars of electrodes mounted on said support member in spaced relation to one another, the at least two pairs of electrodes spaced in a substantially rectangular array, and at least one of said electrodes having a needle configuration for penetrating tissue for in vivo electroporation of cells of the tissue; an electric pulse generator; and an electrical circuit connected to said electrodes and including switching means for selectively connecting at least two opposing pairs of said electrodes of opposite polarity to said pulse generator to permit delivery to alternate opposed pairs of said electrodes, but not all electrodes, proportionate to the distance between said electrodes for electroporation of cells within the electric field generated by said electrodes.
