  • Publication number: 20240341719
    Abstract: A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

  • Patent number: 12082878
    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. In some embodiments, 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.
