<P>PROBLEM TO BE SOLVED: To provide an electrosurgical system which effectively and consistently seals tissue. <P>SOLUTION: An electrosurgical generator is adapted to supply electrosurgical energy to tissue. The electrosurgical generator comprises: an RF output stage adapted to supply the electrosurgical energy to tissue and further adapted to supply an electrical signal having at least one substantially constant value to the tissue to determine an initial tissue impedance response; a sensor circuit adapted to continuously monitor the initial tissue impedance response; and a microprocessor adapted to generate at least one tissue treatment parameter as a function of at least one of the initial impedance, the impedance drop, the impedance minimum value and the first impedance rise. <P>COPYRIGHT: (C)2013,JPO&INPIT |
