Key exclusion criteria
* Untreated significant superficial venous incompetence which, in the opinion of the Investigator, may be the primary source of existing symptoms;
* Deep venous intervention in the target limb or outflow vessels within 6 months of consent;
* Significant peripheral arterial disease with an ankle-brachial index of <0.50 or with incompressible vessels;
* Acute deep venous thrombosis (DVT) within 3 months of consent;
* History of stroke within the last 6 months;
* Flow-limiting venous outflow obstruction central to the intended target sites;
* Insufficient inflow through the treatment vein upon manual augmentation;
* Chronic, diffuse, post-thrombotic femoropopliteal vein disease that, in the Investigator's opinion, would preclude venous valve formation or would inhibit flow through the treatment sites;
* Chronic renal insufficiency with creatinine level of =2mg/dL;
