Abstract
A method of forming a fenestrated tubular support member includes determining a first iso-stiffness curve corresponding to a first function of beam length versus ring width for the first stiffness; determining a second iso-stiffness curve corresponding to a second function of beam length versus ring width for the second stiffness; determining an iso-volume curve corresponding to a third function of beam length versus ring width for a given fenestration volume; identifying a first intersection point where the iso-volume curve intersects the first iso-stiffness curve; and identifying a second intersection point where the iso-volume curve intersects the second iso-stiffness curve. The first section ring width and first section beam length are determined from the first intersection point, and the second section ring width and second section beam length are determined from the second intersection point.
