Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals diagnosed with symptomatic non-obstructive chronic valvular insufficiency of the femoral vein who can provide informed consent.

Probably not a fit

Patients with a history of multiple deep vein thromboses or those with inadequate venous inflow or outflow may not benefit from this study.

What this trial studies

This feasibility study aims to assess the safety of the InnoVein Valve and Delivery System in treating chronic venous insufficiency, a condition where ineffective venous valves lead to blood pooling in the legs. The study focuses on patients with symptomatic non-obstructive chronic valvular insufficiency of the femoral vein. Participants will receive the investigational biocompatible valve, which is designed to restore natural blood flow. The study will monitor safety outcomes related to the valve's implantation and functionality.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate symptoms and improve quality of life for patients suffering from chronic venous insufficiency.

How similar studies have gone: While this approach is novel, similar studies evaluating valve implantation for venous insufficiency have shown promising results.
