New Organ Helps Return Blood Flow

Narine Sarvazyan, Ph.D., professor of pharmacology and physiology at the George Washington University School of Medicine and Health Sciences, has invented a new organ to help return blood flow from veins lacking functional valves. A rhythmically contracting cuff made of cardiac muscle cells surrounds the vein acting as a “mini heart” to aid blood flow through venous segments. The cuff can be made of a patient’s own adult stem cells, eliminating the chance of implant rejection.
