Key inclusion criteria
- Symptomatic CVI subjects, Clinical Etiological Anatomical Pathophysiological (CEAP)
grade 3 to 6;

- Failed compression therapy of at least 6 months' duration;

Can healthy volunteers participate?
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

- 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;

- Hemoglobin level <9.0 mg/dL;

- Platelet count <50,000 or >1,000,000 per mm3;

- Total white blood cell count <3,000/mm3;

- Pregnant or lactating female; positive pregnancy test, women of childbearing potential
must be tested;

- Non-ambulatory patients;
