Scientists use focused rotary jet spinning to produce heart valves in minutes. What's more exciting is that the valves started working immediately when they were implanted in sheep.
valves with synthetic valves. Every year over 100,000 people undergo heart valve operation in the US.
The researchers first created a heart valve-shaped frame and then used air jets to push a liquid polymer into the frame. This led to the development of flawless nanofiber meshwork —- the resulting valve has a porous scaffold where cells can come and grow.
"Unfortunately, current heart valve replacements do not grow alongside the child. Our valves are manufactured using biodegradable polymer fibers that allow for the patient’s cells to attach and remodel the implanted scaffold, eventually building a native valve that can grow and live with the child throughout their life," the researchersSynthetic heart valves are known for their lifetime durability and ability to get patients through billions of.
After testing valves for elasticity, strength, and safety, the researchers wanted to check whether the valve prototype works in a mammal., and their valves are constantly under pressure due to their body’s aggressive calcium metabolism, so the authors decided to go with sheep models.
