About stents

Stents are small (metal) mesh tubes that are implanted into arteries and veins to prevent or treat vessel blockages in the endovascular system and aneurysms in the brain (flow diverters).

Coronary stents (which are typically balloon-expandable CoCr alloy stents), for example, are used as one of the standard treatments in coronary artery disease (such as heart attacks). Several million stents are implanted each year.

The videos below provide an introduction to interventions to treat aneurysms and coronary artery disease.
