A method for generating a lattice cell shape for a stent comprising generating a unit cell model representing a stent cell to be made of a given material, the unit cell model comprising elements each comprising points defining a G-continuous curve, setting a weighting factor to a same value for each one of the points, the weighting factor representing a contribution of a corresponding one of the points to a curvature of an optimal curve, determining a curvature of the G-continuous curve as a function of the weighting factors having the same value, and structurally optimizing the unit cell model by iteratively determining a variable value for the weighting factor value using stress-strain characteristics for the given material, determining a new curvature of the G-continuous curve as a function of the variable value, and minimizing the new curvature, thereby obtaining an optimized curve corresponding to an optimized lattice cell shape.
