Abstract
Methods and systems for sealing biological tissue using high frequency electrical energy determines a first-instance size of the biological tissue based on an initial impedance determination and applies electrical energy to the biological tissue based on the first-instance size determination, during which an in-process parameter is detected. A second-instance size of the biological tissue is determined based on the detected in-process parameter. When the second-instance size is different from the first-instance size, the second-instance electrical energy is different than the first-instance electrical energy; and when the second-instance size is the same as the first-instance size, the second-instance electrical is the same as the first-instance electrical energy. In-process parameter include (i) a value of in-process impedance of the biological tissue, (ii) a rate of change of the in-process impedance of the biological tissue, (iii) a value of in-process integrated power delivered to the biological tissue, or (iv) a combination thereof.
