Sheet Embodiment
[0055]Another method for forming a stent including hollow struts is described referring to FIGS. 26-30. In this embodiment, rather than forming the stent from a wire bent into a stent pattern, the stent pattern is cut into flat sheets, rolled into a tube, and welded to form a stent with hollow struts. As illustrated schematically in FIG. 26, a first sheet 402 and second sheet 404 sandwich a third sheet 406 therebetween. First and second sheets 402, 404 are made from materials that form a finished stent, such as stainless steel, nitinol, MP35N, etc. Third sheet 406 is made from a material that can be removed from between first and second sheets 402, 404 after forming. For example, the materials described in co-pending U.S. application Ser. No. 12 / 500,359, filed Jul. 9, 2009 and incorporated by reference herein, for the outer member can be used for first and second sheets 402, 404, and the materials described therein for the sacrificial or core member can be used as th...
