Improving heart bypass outcomes with 3D-printed blood vessels

The use of 3D-printed blood vessels in heart bypass operations could help limit scarring, pain and infections, scientists say. — dpa

3D-printed blood vessels that closely mimic the properties of human veins could transform the treatment of cardiovascular (heart) diseases, scientists have said.

A team of researchers led by the University of Edinburgh’s School of Engineering in the United Kingdom produced the synthetic vessel from a water-based gel, using a 3D printer with an integrated rotating spindle.
