A collection of sterile devices intended to be used for the endovascular closure of the great saphenous vein (GSV) and associated varicosities as a treatment for varicose veins. It typically includes a surgical adhesive (e.g., cyanoacrylate), syringe, delivery catheter, dilator, introducer and a dispensing gun. The adhesive is typically delivered under ultrasonic control at prescribed intervals throughout the length of the affected vein to adhere the vessel walls together, resulting in the complete and permanent closure of the lumen. This is a single-use device.
