Vesta: distensible multielectrode balloon endometrial ablation

Pages 6

If an impedance for any one electrode is too high, indicating poor tissue contact, the control will not permit treatment to begin. The electrode is monitored three times per second and the generator will energize the electrode, that is farthest below its set point temperature each cycle. Warm-up is programmed to occur within 3 minutes. The controller automatically shifts to 4-minute treatment phase as soon as all electrodes have reached their set points and ends the procedure when treatment is completed.
