BioCoStent

Technology

BioCoStent is an endovascular drug-eluting stent used to treat coronary artery disease.

The coronary stent consists of a metal scaffold made of Cobalt/Chromium alloy coated with biodegradable polymer and retinoic acid.

Diagrammatic representation of the catheter design used for the advancement and deployment of BioCoStent

The stent is attached to a balloon catheter which is advanced through the vascular system to the area where the stenosis is located. There, during balloon inflation, the stent is deployed and permanently positioned for keeping the vessel lumen open.

The local release of the drug on the surface of the dilated arterial lesion aims to limit the rate of restenosis and/or to prevent the further development of atherosclerotic plaque.
