1. A method for making a personalized coronary stent, the method comprising:

  • generating a three-dimensional (3-D) model of an unstenosed geometry of a blood vessel responsive to a 3-D model of an actual geometry of the blood vessel;

    establishing a parametric description of a stent that can be expanded from a collapsed configuration to a final configuration that apposes the unstenosed geometry, wherein the parametric description includes parameters that characterize struts of the stent;

    developing a design for the stent by varying parameters of the parametric description responsive to a design heuristic that includes risk of stent strut breakage during a plastic deformation between the collapsed configuration and the final configuration; and

    embodying the stent, by 3-D printing the stent in the final configuration around an expandable and collapsible mandrel with bridges of the stent in registry with pillars of the mandrel, according to the design for the stent.
