Finite element analysis of balloon-expandable coronary stent deployment: influence of angioplasty balloon configuration.
Today, the majority of coronary stents are balloon-expandable and are deployed using a balloon-tipped catheter. To improve deliverability, the membrane of the angioplasty balloon is typically folded about the catheter in a pleated configuration. As such, the deployment of the angioplasty balloon is governed by the material properties of the balloon membrane, its folded configuration and its att...

متن کاملDISCOVER: Dutch Iliac Stent trial: COVERed balloon-expandable versus uncovered balloon-expandable stents in the common iliac artery: study protocol for a randomized controlled trial
BACKGROUND Iliac artery atherosclerotic disease may cause intermittent claudication and critical limb ischemia. It can lead to serious complications such as infection, amputation and even death. Revascularization relieves symptoms and prevents these complications. Historically, open surgical repair, in the form of endarterectomy or bypass, was used. Over the last decade, endovascular repair has...
متن کامل- s 285 - Development of Test Methods for Mechanical Property Evaluation of Balloon - Expandable CoCr Alloy Stent
The present study aims to establish comprehensive test methods to evaluate the mechanical properties of the intravascular coronary stent with a closed cell design. We focused on three important mechanical properties required to the stent, bending flexibility, radial strength, and longitudinal strength. Test apparatuses and testing procedures were then developed for precise evaluation of those p...
متن کاملInitial experience with the cook formula balloon expandable stent in congenital heart disease.
INTRODUCTION Balloon expandable stents are an integral part in the catheter treatment of congenital heart disease. In the growing child, stents require dilatation to greater diameters over time. The Cook Formula stent is a recent 316 stainless steel open-cell design licensed for peripheral vascular work. METHODS Following extensive ex vivo studies, 112 stents were implanted in 97 children [me...
