Customize blood vessels with 3D printed guides to fight heart disease

The "ring stacking method" is a 3D printing method recently developed by researchers at Wayne State University in Detroit to manufacture custom blood vessels. The method involves the manufacture of expandable and customizable blood vessels using a 3D printer and is expected to improve the treatment of coronary heart disease.

The cause of coronary heart disease is the formation of plaques in the coronary arteries. The plaques weaken the heart muscle over time and may cause heart failure and arrhythmias. One of the most common treatments for this disease is to collect the patient's blood vessels for bypass surgery. However, this method is flawed. On the one hand, once it is determined that the patient needs to undergo bypass surgery, their condition is already evident, which means that their blood vessels are often unavailable. Even if available, collecting blood vessels can cause additional damage to the patient and can also cause infection.
