- Ablation results from antenna broadcasted microwave power field penetration in to tissue over time
- Regular-predictable ablation zone size and shape; unaffected by varying tissue electrical resistance and minimally affected by cooling blood flow
- No return pads to cause extra burns
- Minimum to no pain and no nerve-muscular reaction during energy application (no current flow)
|
- Ablation results from thermal conduction of heated tissue next to electrode spreading outward over time
- Greatly affected by varying tissue properties and adjacent blood flows (heat sink)
- Extra return pad burns from high RF power application (200 to 300 watts)
- Severe pain and nerve-muscular reaction induced during energy application (RF current flow)
