    Abstract: An optimization of electrical characteristics for treatments of tumor or other abnormal cells in culture with sub-microsecond, high-electric field electrical pulses is disclosed. The voltages, pulse widths, and number of pulses are chosen such that the treatment energy is 10-20 J/mL. That is, U = n * Δt * V * I / volume is 10-20 J/mL, in which n is the number of pulses, Δt is the duration of each pulse, V is the voltage, I is current, and volume is the area of parallel electrodes times the distance between them. V divided by the distance between the electrodes can be in an effective range of 6 kV/cm to 30 kV/cm, 60 kV/cm, 100 kV/cm, or higher intensities. Rows of needle electrodes, blade electrodes, or other configurations of electrodes can approximate parallel electrodes.

    Abstract: A sub-microsecond pulsed electric field generator is disclosed. The field generator includes a controller, which generates a power supply control signal and generates a pulse generator control signal, and a power supply, which receives the power supply control signal and generates one or more power voltages based on the received power supply control signal. The field generator also includes a pulse generator which receives the power voltages and the pulse generator control signal, and generates one or more pulses based on the power voltages and based on the pulse generator control signal. The controller receives feedback signals representing a value of a characteristic of or a result of the pulses and generates at least one of the power supply control signal and the pulse generator control signal based on the received feedback signals.

    Abstract: Methods and systems for testing a pulse generator circuit are disclosed. The methods include calculating one or more impedances of a load from applied pulses and comparing the one or more impedances with an expected impedance. The results of the comparison are used to determine whether the pulse generator system is working properly, whether the therapeutic treatment may be initiated or continued, or whether parameters of the pulses should be changed. The pulses may be therapeutic or test pulses, and they may have various parameters of voltage, duration, frequency, or any other electrical parameter. The methods of the disclosure may be performed by a treatment system comprising a controller.

    Abstract: A handheld, therapeutic electrode and connector that are compatible with high voltages from a pulse generator are disclosed. The electrode includes therapeutic terminals on a tip configured to deliver high voltage pulses safely to a patient. The electrode includes sleeves, bosses, wiring channels, and other features that maximize a minimum clearance distance (across non-conductive surfaces) and air clearance between conductive connectors themselves or the connectors and a user, thus preventing dangerous arcing. Internal surfaces and seams are taken into account. The connector and its mating outlet can include similar features to maximize clearance distance. Skirts, skirt holes, and finger stops are also employed, and they can be on either the connector or outlet, or the tip or handle of the electrode.
