| Anatomical eligibility criteria | Treatment of all accessible arteries with a diameter of 3-8 mm | Treatment of accessible main renal arteries with a diameter of 3-8 mm |
| Access | Femoral access (6 Fr) | Femoral access (7 Fr) |
| Wiring | Consider use of extra-support wires or buddy wires in tortuous anatomy | Consider use of extra-support wires or buddy wires in tortuous anatomy |
| Ablation sites | Main renal artery and branches | Main renal artery, 2-3 ablations per artery. The selection of catheter size and ablation site required preprocedural planning with CT/MRA in trials. Final sizing can be done during the renal angiogram before the procedure |
| Arterial wall contact | Ensure appropriate contact of the RF electrodes and the vessel wall Ensure energy delivery (for at least 45 sec, ideally 60 sec) | Ensure complete occlusion of the renal artery after balloon inflation |
| Duration | Simultaneous ablation at 4 points (for at least 45 sec, ideally 60 sec) | 7 seconds per ablation |
