摘要： An elongate electrode is configured to flex and generate plasma to incise tissue. An electrical energy source operatively coupled to the electrode is configured to provide electrical energy to the electrode to generate the plasma. A tensioning element is operatively coupled to the elongate electrode. The tensioning element can be configured to provide tension to the elongate electrode to allow the elongate electrode to flex in response to the elongate electrode engaging the tissue and generating the plasma. The tensioning element operatively coupled to the flexible elongate electrode may allow for the use of a small diameter electrode, such as a 5 μm to 20 μm diameter electrode, which can allow narrow incisions to be formed with decreased tissue damage. In some embodiments, the tensioning of the electrode allows the electrode to more accurately incise tissue by decreasing variations in the position of the electrode along the incision path.

摘要： An integrated gas-enhanced electrosurgical generator. The generator comprises a high frequency power module, a low frequency power module and a gas module. The high frequency power module adapted to generate an electrical energy having a band of frequencies centered around a first frequency, wherein the electrical energy has a first power as the first frequency and a second power lower than the first power at a second frequency lower than the first frequency. The low frequency power module having an input connected to an output of the high frequency module. The low frequency module comprises a resonant transformer comprising a ferrite core, a primary coil and a secondary coil, the secondary coil having a larger number of turns than the primary coil, wherein the resonant transformer has a resonant frequency equal to the second frequency. The gas module is adapted to control a flow of an inert gas.

摘要： 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.
