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.

12. An apparatus comprising:
-
a mandrel that has a generally cylindrical hollow membrane for receiving a balloon and that has a plurality of pillars protruding from an outer surface of the membrane, wherein at least one of the pillars protrudes to a different radius than at least one other of the pillars; and a stent supported on the mandrel by contact of the pillars of the mandrel against bridges of the stent. - View Dependent Claims (13, 14, 15, 16)

19. A non-transitory computer readable medium embodying computer executable instructions which when executed by a computer cause the computer to facilitate the method of:
-
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 according to the design for the stent. - View Dependent Claims (20, 21, 22)
