摘要： A method for electrosurgically sealing a tissue includes steps of: (A) applying a first pulse of RF energy to the tissue; and (B) applying at least one subsequent RF energy pulse to the tissue and keeping constant or varying RF energy parameters of individual pulses of subsequent RF energy pulses in accordance with at least one characteristic of an electrical transient that occurs during the individual RF energy pulses. The method terminates the generation of the at least one subsequent RF pulse upon a determination that the electrical transient is absent.

摘要： A method for electrosurgically sealing a tissue includes steps of: (A) applying an initial pulse of RF energy to the tissue, the pulse having characteristics selected so as not to appreciably heat the tissue; (B) measuring a value of an impedance of the tissue in response to the applied pulse; (C) in accordance with the measured impedance value, determining an initial set of pulse parameters for use during a first RF energy pulse that is applied to the tissue; and (D) varying the pulse parameters of individual ones of subsequent RF energy pulses in accordance with at least one characteristic of an electrical transient that occurs during subsequent RF energy pulses. The method terminates the generation of subsequent RF energy pulses upon a determination that the electrical transient is absent or that a minimum output voltage has been reached.
