Improvement of mechanical performance of bioresorbable magnesium alloy coronary artery stents through stent pattern redesign

Optimized stent pattern design can effectively enhance the mechanical performance of magnesium alloy stents by adjusting strain distribution and evolution during stent deformation, thereby overcoming the limitations imposed by the intrinsic mechanical properties of magnesium alloys. In the present study, a new stent design pattern for...

3D printing of patient specific bioresorbable cardiovascular stents

Cardiovascular diseases, in particular atherosclerosis, is currently the leading cause of death worldwide with increasing numbers due to an aging population. Recently, the first bioresorbable stent (BRS), Absorb GT1 (Abbott, USA) was approved by the FDA, consequently sparking enthusiasm in BRSs and degradable polymeric biomaterials. Polymeric...
