Minimally invasive dermal electroporation device

A device for electroporating and delivering one or more antigens, the device comprising:

• a housing having a distal tip portion;
• a plurality of electrode arrays each coupled to the tip portion, wherein the electrode arrays project from the tip portion and define spatially separate sites, each electrode array includes a plurality of electrodes;
• a pulse generator electrically coupled to at least one electrode of each electrode array;
• a programmable microcontroller electrically coupled to the pulse generator, wherein each electrode is configured to deliver an electroporating pulse to cells of epidermal tissues, and wherein the microcontroller is configured to adjust parameters of the electroporating pulse of each electrode array independently;
• and
• an electrical power source coupled to the pulse generator and the microcontroller, wherein the electrical power source is a battery carried within the housing and configured to power the pulse generator, wherein the battery allows the device to be portable.
