    摘要: The present invention aims to address at least partially the above issues in a much more versatile configuration that will allow more efficient and safer procedures in a broader spectrum of clinical conditions compared to the other electroporators.
    To reach this purpose, a portable equipment for therapeutic transfer of molecules according to the invention comprises electroporation protocol means to control biphasic pulses sequences with a parameters set comprising the number of pulses in each sequence, bipolar shape and duration of each pulse component as well as pause duration between two sequences, means to download said parameters preliminary determined as depending of the transfer protocol. The pulses are provided by a circuit comprising a rechargeable battery that powers a capacitor to generate a burst of biphasic pulses to electrodes at a high voltage, requiring only a control on the voltage of the generated pulses.

    摘要: Disclosed is a system and method for generating time variant and invariant electric fields (E-fields) for various applications. Generating the E-field utilizes high impedance dielectric materials having a collection of three imperative material properties: high permittivity (ϵ), high volume resistivity (ρ) and high maximum allowable E-field stress (φ) and physical geometries that take advantage of the manner in which E-fields are divided or distributed in series capacitance networks. The generated E-field can act upon a subject material, including a gas, liquid or solid, wherein the material is stationary or in motion. The method allows an E-field of given intensity to be set up in the subject material with a significantly lower applied voltage Φa, or conversely, a significantly higher E-field intensity with a given applied voltage Φa. The method forestalls electric conduction current through the subject material, thus significantly reducing electric conduction current, energy consumption, ohmic heating, and preempting electrochemical reactions at the electrode/fluid interfaces. Acoustic energy may also be applied.

    摘要: A method and apparatus are provided for treating biological cellular material with a treating agent using pulsed electrical fields provided by a waveform generator (12). The treatment method includes obtaining an electrode assembly which includes three or more parallel rows of individual electrodes (19). The electrode assembly is applied to a treatment area. Electrically conductive pathways are established between the electrodes (19) and the waveform generator (12) through an array switch (14). Successive electric fields are applied to the treatment area in the form of successive electric field waveforms from the waveform generator (12), through the array switch (14), to adjacent rows of electrodes (19), wherein each successive electric field has the same direction, and wherein polarities of rows of electrodes are reversed successively during the applying of the successive electric fields between adjacent successive rows of electrodes to the treatment area. As a result, the biological cellular material in the treatment area is treated with the treating agent unidirectionally with uniform electric fields with a minimization of the formation of deleterious electrochemistry products at the electrodes.
