Features and benefits
Precision
The proprietary catheter is highly visible under ultrasound, allowing precise delivery of the adhesive. The dispensing gun precisely controls the amount of adhesive, delivering 0.10 cc aliquots with each trigger pull.
Polymerization
Upon contact with blood, the adhesive begins to bond with the intima and compression is applied to close the vein. The adhesive was designed to remain permanently in the diseased vein and is encapsulated by chronic fibrosis.7
Viscosity
The viscosity of the adhesive is specifically designed to minimize migration and embolization.
Flexibility
The adhesive is designed to be soft and flexible, and less likely to be felt by the patient.

Indications
The VenaSeal™ closure system (VenaSeal™ system) is indicated for use in the permanent closure of lower extremity superficial truncal veins, such as the great saphenous vein (GSV), through endovascular embolization with coaptation. The VenaSeal™ system is intended for use in adults with clinically symptomatic venous reflux as diagnosed by duplex ultrasound (DUS).

| Catheter |
The catheter is 5 Fr with an effective length of 91 cm, laser markings at 3 cm and 85 cm from the tip, and high echogenic visibility. |
| Introducer |
The introducer is 7 Fr with an effective length of 80 cm, with 10 mm spaced circumferential markings along its length for measuring retraction length during the VenaSeal procedure. |
| Dilator |
The dilator is 5 Fr with an effective length of 87 cm. |
| Syringe |
The 3 cc syringes are graduated Monoject™* Luer Lock syringes, each with a standard threaded Luer Lock connector. |
| Dispenser Tips |
The dispenser tips are each comprised of a stainless steel, 1.5 mm ID, 3.8 cm length hypotube with a Luer Lock connector. |
| Guidewire |
The guidewire is a 0.035 in, 180 cm straight floppy-tip guidewire. |
