A coating for life: Biodegradable fibers advance stent technology and brain surgery, then disappear

Stents that keep weakened and flabby arteries from collapsing have been true life-savers. But after six months, those stents are no longer needed -- once the arteries are strengthened, they become unnecessary. Previously, ...

Zinc: The perfect material for bioabsorbable stents?

( —In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked ...

Math from the heart: Simulating stent design and coating

Suncica "Sunny" Canic was good at math in school, so that's what she pursued as a career. But she always liked medicine, too. When she moved to Houston, Texas, and met some cardiologists at a party, she started talking with ...
