NONTHERMAL ABLATION Cyanoacrylate Closure

The VenaSeal™ closure system delivers immediate and lasting vein closure with its proprietary medical adhesive formula.1-5

  • Simple, segmental procedure with no risk of thermal nerve injury
  • No tumescent anesthesia — limited needle sticks 
  • Less pain and bruising than thermal energy treatment4
  • No post-procedure compression stockings required*3,4
