New approaches in catheterization techniques have led to the development of numerous therapeutic procedures. Medical catheters consist of tubes that are inserted into the body vessel, cavity or duct to allow the fluids, medications or gases to drain the urine or fluids from the body. There are numerous catheters for various therapeutic areas, such as urology, cardiovascular, neurovascular, ophthalmic and gastrointestinal. Cardiac catheterization is a minimally invasive procedure performed by using catheters, wires and x-ray to treat and diagnose problems in the blood vessels of the heart. According to a study by the American College of Cardiology, approximately 800,000 deaths due to cardiovascular diseases are reported in the U.S., which indicates increase in the use of pulmonary artery catheters.
