    Abstract: This invention comprises an improved electroporation electrode system comprising a single needle and a ring or donut shaped electrode wherein the difference in surface area of the electrodes provide for a substantial reduction of current density near the surface of the treated tissue and a more concentrated current density sufficient for electroporation only in tissues adjacent to the terminal portion of the single needle electrode. Thus, this invention provides for targeting specific tissue for electroporation and also should provide for lessening the sensation of electric current in the treated tissue.

    Abstract: This invention provides a novel method of tissue electroporation that eliminates the need for electrodes that conduct electricity to the tissues. This invention creates electric currents and fields sufficient for porating cell membranes for improving the delivery of polynucleotides such as plasmid and linear DNA and RNA constructs, and polypeptides such as antigen protein constructs into mammalian eucaryotic cells purely by magnetic field pulses that does not require the use of contacting electrodes to conduct electric or ionic current. This invention thus provides a method for improving transfection and immunogenicity of pharmaceutical substances without direct contact with a living body, and may be called magnetopermeabilization. A concomitant aspect of the invention is the method by which a drug such as a solution containing DNA is delivered to a targeted tissue bed that is optimal in conjunction with magnetopermeabilization for maximal transgene expression and drug effect.
