摘要: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device (300), such as glue gun, that operably connected to delivery catheter (202) advanced across zone (400). The used deliver one, two, or more boluses of media (V2, V2') (e.g., cyanoacrylate) occlude (400) different spaced-apart sections External compression also applied by element, hand (640) multifunctional ultrasound transducer (630), portions prior during introduction (V2. V2').
