A search of solutions for large-scale miniature heart pumps
A scientist at Mississippi State University plays a key role in a national research effort to develop an artificial heart small enough for use in infants and children. Mechanical engineer Greg Burgreen, an authority in the field of computational fluid dynamics, focuses on the complexity of the flow of blood through a heart Jarvik and the University of Maryland project to design implantable ventricular assist devices for children.Burgreen, research associate professor of SimCenter (simulation center) of the ERC-ex Universitys Engineering Research Center. He said later that the Jarvik heart pumps used in adults are only the size of D-cell batteries, but still create blood-flow problems in children because of their smaller body size and limited blood volume. Our goal is to
miniaturize the size of adult pump for use in a child or a child, he said. However, in this size, the rotor or turbine inside the pump should run at 24,000 rpm, like a blender (food).damaged. Despite the enormity of the challenge, he said, researchers hope to design a pump no larger than the size of a AA battery for children, and about half that for children. But Burgreen said, there is a limit to what man can replicate with the engineering that is what our Creator has everything perfect. He grew up near Huntsville, Alabama, and graduated in 1981 from East High School limestone, came to MSU two years ago, after eight years with the University of Pittsburgh Medical Research Group.
New York City-based Jarvik Heart Inc. recently signed a contract of $ 5,000,000 from the
National Institutes of Health to develop a heart pump for children. At the head of the research project of five years, his namesake, Dr. Robert Jarvik, who developed the famous Jarvik 7 pump blood. Dr. Bartley Griffith of the University of Maryland, the former chief of cardiac surgery at Pittsburghs School of Medicine, is a project co-director.awarded - the methods of computer simulation technology, generating high
