  • Publication number: 20240390589
    Abstract: A jet injection and electroporation device for use with an agent cartridge defining a volume containing a pre-measured dose of agent therein, the electroporation device including a housing having an axis extend therethrough, a nozzle at least partially positioned within the housing, and a cavity sized to receive at least a portion of the agent cartridge therein. The device also includes an array having a plurality of electrodes extending therefrom, a propulsion cartridge configured to operatively engage the cartridge when the agent cartridge is positioned within the cavity; and a power supply in electrical communication with the array.

  • Publication number: 20200289818
    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.
