Scientists have created a human-made blood vessel using 3D printing technology, which could aid in treating heart diseases.
These strong and flexible tubes, made from a water-based gel and printed with a rotating machine, mimic real blood vessels. Blood vessels are tiny tubes that transport blood to and from your heart.
This innovative project is led by the University of Edinburgh School of Engineering. The goal is to use these synthetic vessels to reduce the risk of infection during some surgeries. The artificial blood vessels are extremely small, with some being just 1 millimeter thick, making them similar in size to natural vessels.
These new blood vessels are expected to be particularly useful in heart bypass operations. A heart bypass, also known as a coronary artery bypass graft, is a procedure that helps people with heart disease by improving blood flow around the heart. Typically, surgeons use blood vessels from a patient’s leg, chest, or arm for the operation.
However, with this new technology, doctors might be able to use 3D-printed vessels instead.
Researchers believe these 3D-printed blood vessels could integrate more easily into a patient’s body. Dr. Norbert Radacsi, the project’s main investigator, says that with further testing and development, improved treatment options for patients with cardiovascular disease could become a reality.
