This invention is directed to a novel method for direct in vivo electrotransfection of a plurality of cells of a target tissue. In the method, the target is perfused with a transfection solution. An exterior electrode is positioned so as to surround at least a portion of the target tissue. One or more interior electrodes are placed within the target tissue. The perfusion and the application of the interior and exterior electrodes may be performed in any particular order. After the perfusion and the positioning of the electrodes, both interior and exterior, an electric waveform is applied through the exterior electrode and the interior electrode to transfect the cells in the target tissue.

Esta invención se dirige a un método de la novela para el electrotransfection in vivo directo de una pluralidad de células de un tejido fino de la blanco. En el método, la blanco se inunda con una solución del transfection. Un electrodo exterior se coloca para rodear por lo menos una porción del tejido fino de la blanco. Unos o más electrodos interiores se colocan dentro del tejido fino de la blanco. La perfusión y el uso de los electrodos interiores y exteriores se pueden realizar en cualquier orden particular. Después de la perfusión y de colocar de los electrodos, interiores y exteriores, una forma de onda eléctrica se aplica a través del electrodo exterior y del electrodo interior al transfect las células en el tejido fino de la blanco.
