Chocolate PTCA Balloon Catheter for pre-dilatation of an occluded circumflex and second obtuse marginal arteries - Case Study

Incomplete stent expansion and malapposed stent struts are a predictor of subacute and late stent thrombosis. Appropriate lesion preparation prior to stent implantation is necessary to assure complete stent expansion and stent strut apposition. This is of particular importance in challenging lesions, in particular those with calcific plaque. The goal of the pre-dilatation is to obtain optimal luminal diameter prior to stenting without causing any significant dissections. There are few devices available that are specifically designed to facilitate predictable dilatation while minimizing the risk of flow-limiting dissection.
