Artificial blood vessels made using a biodegradable mesh tube as a scaffold for aorta cells have shown positive results in an animal study and a clinical trial has begun, according to findings presented online through the American Heart Association. The process for the new blood vessel to develop and the mesh structure to dissolve takes two months. Tests on primates showed the synthetic blood vessels can endure frequent needle sticks. A clinical trial in Europe is underway, and a study in the U.S. has been granted FDA authorization.
