By adopting a modified cell-printing technique, engineers at Pohang Univ. of Science and Technology (POSTECH) in South Korea have created the most functional 3D-printed blood vessel to date.
Blood vessels carry blood throughout the body, providing major organs with the oxygen that is essential to their ability to function.
Clogged blood vessels or arteries occur as a result of plaque buildup on the inner cell walls; clogs greatly increase the likelihood of heart attacks, strokes, and death.
In fact, cardiovascular diseases are the leading cause of death worldwide — every year, doctors perform over one million vascular bypass surgeries in the U.S. alone.
This procedure diverts blood flow in clogged blood vessels to restore normal blood circulation and reduce the risk of future heart attacks and strokes. The mortality rate of this surgery is low, but it may be more effective to replace blocked vessels than attempt to divert the blood flow...
