Aspects of the present invention relate to electroporation devices and
methods of using same to effectively facilitate the introduction of a
biomolecule into cells of a selected tissue in a body, in particular skin
such as intradermic or subcutaneous tissue. In some aspects, the present
invention is a skin EP device, which produces a pulse of energy and
delivers same to the skin tissue using a skin electrode array and
maintains a constant current in the same skin tissue based on user input,
including a preset current, and allows the storage and acquisition of
current waveform data.
