“In the 1980s, researchers discovered that the molecules in the softer segments helped make the polymer more blood-friendly because the platelet cells that cause clots didn’t stick to them as much. Since then, engineers have worked to make polyurethanes with even better biocompatibility by changing the chemical structure of the hard segments so they don’t accumulate platelets as much, either. But polyurethane isn’t the only polymer that’s widely-used as a biomaterial.”
