Exclusion Criteria:

  • Active bacterial infection or fungal infection on the day of the ablation.
  • Patients with implantable pacemakers or other electronic implants.
  • Platelet count less than 50,000/mm cubed.
  • Patients with uncorrectable coagulopathy at the time of ablation.
  • Currently breastfeeding or pregnant (latter confirmed by serum pregnancy test, per site's SOC).
  • Physical or psychological condition which would impair study participation.
  • ASA (American Society of Anesthesiologists) score of great or equal to 4.
