for chronic venous Insufficiency (CVI)
The ClosureFast™ procedure uses radiofrequency energy to treat patients with superficial vein disease. Its segmental approach features an overlap of 0.5 cm at each treatment segment, designed to eliminate gaps in treatment.
Data are from ClosureFast 7F studies. ClosureFast 6F catheter is designed to provide the same outcomes as established by ClosureFast 7F catheter.
ClosureFast catheter is now available in 6F, designed for†‡:
The ClosureFast procedure features a patented overlap of 0.5 cm at each thermal treatment segment, eliminating gaps between segments ― for lasting vein closure.1,3
Note: 3 cm (7F) heating length available for shorter segments.

7F catheter
Data are from ClosureFast 7F studies. ClosureFast 6F catheter is designed to provide the same outcomes as established by ClosureFast 7F catheter.
The ClosureFast endovenous radiofrequency ablation (RFA) catheter is intended for endovascular coagulation of blood vessels in patients with superficial vein reflux.
Adverse events may include hematoma, phlebitis, skin injury, nerve injury, thrombophlebitis, thrombosis, and/or pulmonary embolism.
