Cook Venous Valve System for Treatment of Chronic Venous Insufficiency

May 15, 2026 updated by: MED Institute Inc.

First-in-Human Early Feasibility Clinical Evaluation of Safety, Efficacy and Utility of the Cook® Venous Valve System for Treatment of Chronic Venous Insufficiency

The purpose of this study is to learn about the safety, efficacy and utility of a medical device called the Cook® Venous Valve System. This device, percutaneously placed in the leg, is meant to help the blood flow correctly through the veins in the leg.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cook® Venous Valve System
The Cook® Venous Valve is a permanent prosthetic, bicuspid, one-way flow valve designed to be percutaneously implanted into the peripheral deep venous system. The Cook® Venous Valve Delivery System is used to percutaneously deliver the Cook® Venous Valve into the deep venous system.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Freedom from major adverse events in the first 30 days
Time Frame: 30 days after enrollment
The primary safety endpoint is freedom from major adverse events (MAE) in the first 30 days, where MAE is defined as: death, clinically-driven reintervention, bleeding requiring transfusion, flow limiting dissection of the target vessel, or clinically significant deep vein thrombosis (DVT), pulmonary embolism, or device migration.
30 days after enrollment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Freedom from MAE at three months, six months, and 12 months
Time Frame: Three months, six months, and 12 months after enrollment
The secondary safety endpoint is freedom from MAE at three months, six months, and 12 months.
Three months, six months, and 12 months after enrollment
