Abstract
Power circuitry for cold plasma generation; optionally plasma for therapeutic use. Cold plasma generation occurs at the distal end of a catheter-like device which is flexible, narrow (e.g., less than 5 mm in diameter), and longitudinally extended to reach, e.g., 50-100 cm into body cavities. A cable used for power transmission is a part of the power generating circuit, its intrinsic impedance being a major contributor to and constraint on the time constant of an entraining RC circuit whose resonant frequency entrains the frequency of power generation. In some embodiments, inductive transformer coupling to the entraining/transmission line circuit is used to generate voltage gain. In some embodiments, transformer coupling is divided into a plurality of stages. This potentially enables practically achieving high transmission frequencies with higher gain, lowered sensitivity to variability in distal portions of the entraining RC circuit, and/or longer transmission lines compared to a single-stage transformer configuration.
