Participation Requirements

• Sex:

  ALL

• Eligible Ages:

  18 and up

Participation Criteria

Inclusion Criteria:

* Symptomatic CVI subjects, Clinical Etiological Anatomical Pathophysiological (CEAP) grade 3 to 6;
* Failed compression therapy of at least 6 months' duration;
* Deep system venous reflux characterized by \>1 second reflux time;
* Presence of at least one target site within the target vessel.

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;
* 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;
