    Abstract: Described is a device and method for administration of molecules to tissue in vivo for various medical applications, the device comprising a single hypodermic injection needle and at least two spaced elongate electrodes which provide for the ability, when the needle is inserted into tissue, such as skin or muscle, to pulse tissue with a non-uniform electric field sufficient to cause reversible poration of cells lying along or in close proximity to the track made by the needle upon its insertion into said tissue.

    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 translation: 本发明包括改进的电穿孔电极系统,其包括单针和环形或环形电极,其中电极的表面面积的差异大大降低了处理组织表面附近的电流密度,并且更集中的电流密度足够 仅在与单针电极的末端部分相邻的组织中进行电穿孔。 因此,本发明提供靶向用于电穿孔的特定组织,并且还应当提供减少处理组织中电流的感觉。
