There is now a 3-D elastic membrane made of a soft, flexible, silicon material that is precisely shaped to match the heart's epicardium. Current technology is two-dimensional and cannot cover the full surface of the epicardium or maintain reliable contact for continual use without sutures or adhesives. The 3-D device was created by an international team of biomedical engineers and materials scientists and Igor Efimov, Ph.D., at the School of Engineering and Applied Science at Washington University in St. Louis.
