摘要：
A method for generating a lattice cell shape for a stent comprising generatingaunit cell model representing a stent cell to be made of a given material, theunitcell model comprising elements each comprising points defining a G2-continuouscurve, setting a weighting factor to a same value for each one of thepoints, the weighting factor representing a contribution of a correspondingoneof the points to a curvature of an optimal curve, determining a curvature oftheG2-continuous curve as a function of the weighting factors having the samevalue, and structurally optimizing the unit cell model by iterativelydetermining avariable value for the weighting factor value using stress-straincharacteristicsfor the given material, determining a new curvature of the G2-continuous curveas a function of the variable value, and minimizing the new curvature, therebyobtaining an optimized curve corresponding to an optimized lattice cell shape.
