More research is needed, but recent developments suggest “disappearing” coronary stents may not be that far away.

For nearly 30 years, coronary stents have had one thing in common: They are composed of a permanent scaffold structure that helps keep a narrowed artery open and blood flowing. Changes in the materials used to make stents have improved their safety and effectiveness.
