Designing Drug-Eluting Stents to Control Release Kinetics and Reduce Restenosis

Quick fact

A drug-eluting stent releases its medication over weeks to months, and adjusting the release rate is so critical that a too-rapid release can fail to prevent restenosis, while a too-slow release can delay healing and increase the risk of blood clots.

Why this is interesting

You've probably seen a stent as a simple wire mesh that props open a blocked artery. But how does that same mesh secretly deliver a drug to keep the artery from closing up again?
