Arm | Intervention/treatment |
---|---|
Experimental: VenaSeal™ Closure System
CEAP 2-5 subjects will be randomized to VenaSeal™ Closure System vs. ETA or Surgical Stripping
|
Device: VenaSeal™ Closure System
The VenaSeal™ closure system is the non-tumescent, non-thermal, non-sclerosant device that uses a proprietary medical adhesive delivered endovenously to close the vein. |
Active Comparator: Endothermal Ablation (ETA)
CEAP 2-5 subjects will be randomized to either VenaSeal™ Closure System or ETA
|
Device: Endothermal Ablation (ETA)
ETA includes EVLA that uses laser or RFA that uses radiofrequency heating to close the vein. Heat is applied in both EVLA and RFA therapies to close the vein. Subject can be treated with either EVLA or RFA if randomized to ETA arm per site's standard practice. Other Names:
|
Active Comparator: Surgical Stripping
CEAP 2-5 subjects will be randomized to either VenaSeal™ Closure System or surgical stripping (outside of the United States only)
|
Procedure: Surgical Stripping
Surgical stripping involves stripping (removal) of the diseased vein via surgical procedures. |
VenaSeal™ Closure System VLU Study
CEAP 6 active leg ulcer subjects will not be randomized to a comparator, all subjects will be treated with VenaSeal™ Closure System
|
Device: VenaSeal™ Closure System
The VenaSeal™ closure system is the non-tumescent, non-thermal, non-sclerosant device that uses a proprietary medical adhesive delivered endovenously to close the vein. |
