Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 13:
14. A method for delivering an electrotherapeutic signal to biological tissue in electrical communication with an electrosurgical instrument, the method including:
measuring a first reference impedance of the biological tissue after a time interval following commencement of a desiccation phase;
determining a first termination criterion for the desiccation phase based on the measured first reference impedance following commencement of the desiccation phase;
delivering a first electrotherapeutic signal to the biological tissue during the desiccation phase, the delivered first electrotherapeutic signal controlled according to an electrotherapeutic plan;
terminating the desiccation phase in response to the first termination criterion being met;
measuring a second reference impedance of the biological tissue following termination of the desiccation phase;
determining a second termination criterion for a vessel welding phase based on the measured second reference impedance prior to commencement of the vessel welding phase;
delivering a second electrotherapeutic signal to the biological tissue during the vessel welding phase; and
terminating the vessel welding phase in response to the second termination criterion being met.
