Apparatus for treating venous insufficiency using directionally applied energy

摘要: A catheter introduces electrodes in a vein for minimally invasive treatment of venous insufficiency by the application energy to cause selective heating vein. The is positioned within be treated, and on are moved toward one side RF applied directional manner from at working end localized corresponding shrinkage adjacent tissue, which may include commissures, leaflets ostia. Fluoroscopy or ultrasound used detect After treating section vein, can repositioned place treat different sections until all desired valves repaired rendered functionally competent.
