Abstract
A method of making a stent includes a three-dimensional printer receiving a dataset corresponding to a three-dimensional precursor stent. The three-dimensional printer forms a precursor stent. The precursor stent comprises a plurality of bands disposed adjacent to each other, wherein each band comprises a plurality of struts connected by a plurality of crowns, and a plurality of connectors connecting each band to an adjacent band. The precursor stent is processed to remove a selected number of the plurality of connectors between adjacent bands such that at least one connector between each set of adjacent bands is removed. In an embodiment, only one connector remains between each adjacent band after the selected number of connectors have been removed.
