摘要：
Abstract: An electrosurgical method is provided to seal biological tissue comprising providing RF power to the tissue during an RF power delivery time interval comprising: measuring a change in impedance of the tissue with respect to RF energy delivered to the tissue during an initial portion of the time interval; selecting an RF power delivery profile, based at least in part upon the measured change in impedance of the tissue with respect to RF energy delivered to the tissue; and imparting RF power to the tissue according to the selected RF power delivery profile during a latter portion of the time interval.
