Editor's Notes
- #17: he ClosureRFS Stylet is the only intravascular ablation device specifically cleared by the FDA for the treatment of incompetent perforator veins. This minimally invasive outpatient treatment can be either the primary procedure or an adjunct to saphenous vein ablation with the VNUS ClosureFASTâ„¢ catheter
