Damaged hearts and blood vessels could be sealed with a new glue developed by researchers.

Called a hydrophobic light-activated adhesive, scientists believe that it could be used during surgery to stop bleeding and also used to repair heart defects.

The scientists created a blood-resistant adhesive that binds to wet cardiovascular tissues and can be specifically set using ultra-violet light.

Dr Sanjay Thakrar, a Research Adviser at the British Heart Foundation, said: “The cardiovascular system is a dynamic environment where there is continuous blood flow and tissue contractions and existing glues often don’t work well in these conditions.

“These researchers seem to have found an innovative way to overcome these issues, which could be especially useful during minimally invasive procedures.”

“As the scientists only measured the effectiveness of the glue over a short time period, it is important to see how the glue performs for longer durations. Additionally, as this research was conducted in animals, further studies are needed to see if it is safe and works in people.”
