1. A surgical generator configured to generate and provide controlled electrical power of a therapeutic signal to biological tissue in electrical communication with an instrument, the surgical generator comprising:
a control circuit in communication with an electrical-energy source, the electrical-energy source electrically coupled to the instrument and configured to generate the therapeutic signal, the control circuit configured to:
control the electrical power of the therapeutic signal provided to the biological tissue during a portion of a non-sealing therapeutic phase according to a therapeutic plan by increasing the electrical power as a function of resistance, wherein the electrical power decreases to a non-zero level between the non-sealing therapeutic phase and a subsequent therapeutic phase.
