Title: VenaSeal Sapheon Closure System vs. Radiofrequency Ablation for Incompetent Greater Saphenous Veins
Brief Summary: The VeClose pivotal study was a controlled, randomized, prospective, multicenter, pivotal study in which patients with venous reflux in the great saphenous vein (GSV) were treated with either the VenaSeal closure system (VenaSeal SCS) or radiofrequency ablation (RFA) therapy.
