Arteries Currently in research and development are artificial arteries for use in coronary bypass operations and to replace damaged blood vessels in the leg. One vascular graft in development is made of collagen, an animal protein, that is formed into a tube. The graft is designed to allow a patient's own cells and blood vessels to populate the artificial vessel. This precludes rejection by the body and turns this non-living product into a living blood vessel that can contract and dilate as needed. (1) |
