Harvard’s synthetic heart valve is designed to grow in step with the human body
Harvard’s Wass Institute and John A. Paulson School of Engineering and Applied Sciences created what they call
. This implant can be manufactured in minutes using a spun-fiber method that lets them shape the valve’s delicate flaps on a microscopic level — ready to be colonized by the patient’s living cells, developing with them as they mature., the team’s 2017 artificial heart valve that employed many of the same principles.
In the researchers’ test on a living sheep, the FibraValve “started to function immediately, its leaflets opening and closing to let blood flow through with every heartbeat.” Additionally, they observed red and white blood cells and fibrin protein collecting on the valve’s scaffolding within the first hour. The scientists say the synthetic valve showed no signs of damage or other problems.
