Abstract:To reduce in‐stent restenosis (ISR), caused by an elastic recoil stent at the initial bend of the artery, it is proposed to use stents with FG bridges, the bending stiffness of which depends on their location. The distribution of bending stiffnesses of FG bridges is studied depending on the initial bend of the artery. The bending of the FG cardiovascular stent is modeled by the bending of a beam with concentrated elastic hinges. Several methods of adapting the stent to the initial bending of the stented sectio… Show more
