  • Patent number: 11490948
    Abstract: 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 ?m to 20 ?m 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.

  • Patent number: 11478293
    Abstract: An electrosurgical generator having connectors for an electrosurgical instrument including a high-voltage generator electrically connected to the connectors and produces a high-frequency alternating current in its activated state and output said high-frequency alternating current via the connectors. The electrosurgical generator has an effective power determination unit including a phase shift determination unit that supplies an output signal representing a phase shift between the current and the voltage of an alternating current output during operation. The phase shift determination unit produces a pulsed DC voltage signal, in which the pulse width reflects a time difference between the zero crossings of the current and the voltage—and consequently the phase shift—and to process the pulsed DC voltage signal by way of a low-pass filter to form a low-pass filter output signal, the magnitude of which depends on the pulse width of the pulses of the pulsed DC voltage signal.
