This objective of this feasibility study is to evaluate the safety of the InnoVein Valve and Delivery System for treatment of chronic venous insufficiency.

Chronic Venous Insufficiency occurs when the venous wall and/or valves in the leg veins are not working effectively, making it difficult for blood to return to the heart from the legs.The core etiology of the disease stems from increased venous pressure and incompetent venous valves leading to regurgitation of blood that accumulates in the legs. It has been shown that implantation or recreation of a functional valve can lead to clearance of excess blood and resolution of symptoms.

The InnoVein Valve and Delivery System is a new, investigational biocompatible valve intended to support natural flow in vessels in patients with Chronic Venous Insufficiency. The purpose of this study is to assess the safety of the InnoVein Valve and Delivery System for treatment of Chronic Venous Insufficiency.
