1. A method of forming a fenestrated tubular support member, the formed fenestrated tubular support member comprising a first section having a first pattern of successive first section annular rings connected by respective first section axial beams, and a second section having a second pattern of successive second section annular rings connected by respective second section axial beams, wherein each of the first section annular rings has a first section ring width and each of the first section beams has a first section beam length, wherein each of the second section annular rings has a second section ring width and each of the second section beams has a second section beam length, and wherein the first section has a first stiffness and the second section has a second stiffness different than the first stiffness, the method of forming the fenestrated tubular support member comprising:
- 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,wherein 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.

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.
