METHOD AND APPARATUS FOR CONTROLLING A SURGICAL ABLATION DEVICE
摘要
<p>A method and apparatus for controlling a surgical ablation device. Two electrodes of an ablation device against the surface of tissue. The tissue impedance is measured between the electrodes. The electrodes are energized based on the measured tissue impedance. If the measured tissue impedance is between a first threshold impedance and a second threshold impedance, the electrodes are energized to output a substantially constant wattage. If the measured tissue impedance is greater than the second threshold impedance, the electrodes are energized to output a variable wattage, the variable wattage being inversely related to the impedance of the tissue.</p>
