Quick Answer. An inferior vena cava filter is a cone-shaped metal device that prevents blood clots from traveling to the lungs, according to Cleveland Clinic. Doctors place this device in the inferior vena cava to catch blood clots that have broken loose, explains the University of Michigan Health System.
The superior vena cava returns blood from the upper body to the heart, and the inferior vena cava returns the blood from the lower part of the body. The superior vena cava is thin-walled, and the blood is under low pressure. It lies near lymph nodes in the chest. Therefore, when the lymph nodes or the aorta of the heart get bigger, the superior vena cava is squeezed, blood flow slows, and complete blockage may occur.
