Abstract
A method including generating a 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 is expanded from a collapsed configuration to a final configuration that apposes the unstenosed geometry, 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, embodying the stent according to the design for the stent, inserting the stent into a blood vessel in its collapsed configuration, maneuvering the stent through the blood vessel to a stenosis, and expanding the stent to its final configuration.
