Title
(EN) MANUFACTURING PROCESS FOR POLYMERIC STENTS
(FR) PROCESSUS DE FABRICATION POUR STENTS POLYMÉRIQUES
Abstract
(EN)
A method of fabricating a stent delivery device is disclosed. The method comprises forming a polymeric tube by using extrusion, the tube being drawn during extrusion so that a diameter of the formed tube is less than a target diameter; radially deforming the formed tube so that the deformed tube comprises the target diameter; forming a stent from the deformed tube, wherein forming the stent includes laser machining a stent pattern in the deformed tube with an ultra-short pulse laser; and crimping the stent on a support element, wherein a temperature of the stent during crimping is above an ambient temperature.
