The VIVA RF electrode is single electrode which is designed to be used in multiple nodules. Traditional single electrodes make the fixed ablation volume, but it is able to make the varisized ablation volume by adjust an active tip.
It has a radio-paque marker which shows the position of electrode clearly on the fluoroscopic image.
Adjustable exposure length provides dynamic treatment options:
-Multiple nodules with different sizes.
-Decreasing pressure during coagulation by stepwise deployment.
-Saving normal tissue by making the varisized ablation volume.
