Intermittent Pneumatic Compression Device Assessment in Patients with Severe Arterial and Venous Disease of the Lower Extremity


About this study

The purpose of this study is to determine whether a specific external compression pump called the AVT pump can improve blood flow to the skin of the feet in patients with circulatory problems involving the arteries or veins of the legs. The use of the AVT pump in this study is considered investigational, which means it has either not been approved by the Food and Drug Administration (FDA) for routine clinical use or for the use described in this study.
