Bioabsorbable coronary stents.
Placing a coronary stent during angioplasty minimizes reduces of acute vessel occlusion [1] and restenosis [2]. Although permanent metallic stents are effective in preventing recoil and late restenosis after coronary angioplasty, they continue to have limitations such as stent thrombosis and mismatch of the stent to the vessel size. In-stent restenosis is the major shortcoming of conventional (...
متن کاملContemporary Reviews in Interventional Cardiology Bioabsorbable Coronary Stents
Percutaneous coronary intervention (PCI) with bioabsorbable stents has created interest because the need for mechanical support for the healing artery is temporary, and beyond the first few months there are potential disadvantages of a permanent metallic prosthesis. Stents improve immediate outcomes, including profoundly reducing acute vessel occlusion after PCI by scaffolding intimal tissue fl...
متن کاملA corrosion model for bioabsorbable metallic stents.
In this study a numerical model is developed to predict the effects of corrosion on the mechanical integrity of bioabsorbable metallic stents. To calibrate the model, the effects of corrosion on the integrity of biodegradable metallic foils are assessed experimentally. In addition, the effects of mechanical loading on the corrosion behaviour of the foil samples are determined. A phenomenologica...
متن کاملDegradation Model of Bioabsorbable Cardiovascular Stents
This study established a numerical model to investigate the degradation mechanism and behavior of bioabsorbable cardiovascular stents. In order to generate the constitutive degradation material model, the degradation characteristics were characterized with user-defined field variables. The radial strength bench test and analysis were used to verify the material model. In order to validate the n...
متن کاملA Review on Biodegradable and Bioabsorbable Stents for Coronary Artery Disease
Coronary artery disease (CAD) is one of the prominent causes of demise in the world. Despite large number of study reports on pathogenesis of atherosclerosis and the development of ischemic heart disease there are numerous questions that are unrequited. About 70% of the risk factors associated with the CAD events are addressed by the classic factors while the other 30% of the CAD events do not ...
