Abstract
Methods and systems of fabricating a polymeric stent are disclosed herein. Methods are disclosed that include forming a polymeric tube using extrusion, radially deforming the formed tube so that the deformed tube comprises a target diameter, forming a stent from the deformed tube, and forming a stent from the deformed tube. The stent is formed by laser machining a stent pattern in the deformed tube with an ultra-short pulse laser. Disclosed methods further include crimping the stent on a support element, wherein a temperature of the stent during crimping is above an ambient temperature.
