Abstract

A method of fenestrating the support structures (4) of an endovascular stent (100) at desired locations and in a desired pattern within the stent is disclosed, with increased efficiency, economy, and reliability over conventional manufacturing techniques. Such fenestrations (9) may be used to allow placement of longitudinal rails (7) throughout some or all of the length of the stent to improve stent flexibility and strength while retaining or improving upon other desirable qualities of existing endovascular stents.
