IVC stands for the inferior vena cava. It is one of the most vital veins that a person needs for survival. The function of this vein is to carry the deoxygenated blood from all of the organs of the body back to the lungs and the heart for oxygenation. The filter for the IVC was developed to prevent blood clot formation in the blood stream. However, according to recent research, these filters have failed to perform well, causing grave health problems in patients. If this is also the case with you, then it is vital that you file an IVC filter lawsuit.
