ICT Valvular Leak Sealer Reconstruction System

ICT is an Internal Compression Therapy for dysfunctioning vein valves. The procedure is also called percutaneous valvuloplasty.

Unlike standard therapies for superficial venous insufficiency—which often eliminate or destroy the problematic vein (via heat ablation, embolization, or surgical stripping)—the ICT Valvular Leak Sealer Reconstruction System by Invamed offers a valve-preserving strategy. Using precise sealing and support around the insufficient venous valve segment, this minimally invasive device supports restoration of natural blood flow dynamics, striving to eliminate reflux while retaining vessel integrity.

Reconstructive Venous Valve Treatment
  • Targets incompetent valves in the superficial vein (commonly the great or small saphenous veins), sealing the leaky valve leaflets instead of ablating or removing the vein.
  • Helps maintain normal venous return and overall vein physiology, reducing risk of collateral vein overload or new varicosities.
  • Employs an implant or sealing device designed to reposition and reinforce the valve cusps, closing the regurgitant gap.
  • Can be introduced via a percutaneous approach, guided by ultrasound or endovenous imaging—limiting dissection and promoting rapid recovery.
  • By not destroying or removing the saphenous segment, the system maintains potential future access for coronary or peripheral bypass grafting.
  • Encourages physiological drainage in the treated limb, diminishing post-procedure edema, discomfort, or long-term complication rates associated with vessel loss.
  • Constructed from medical-grade alloys or polymer composites that resist fatigue under repeated venous pressure cycles.
  • Low-profile design seeks to minimize localized thrombogenic risk and adapt to variations in valve morphology.
  • Indicated for;
    Deep Venous Insufficiency (DVI) • Superficial Venous Insufficiency (SVI)

ICT is an implant device in which a gel implant consisting of a mixture of hyaluronic acid and n-butyl-cyanoacrylate (n-BCA) is placed around the periphery of the incompetent deep venous valve or terminal valve of the saphenofemoral junction (SFJ) and in the fascia layer, rigid support.
