Vorrichtung zum Laserstrahl-Strukturieren von bioresorbierbaren, intraluminalen Gefäßwandstützen

摘要

During the manufacturing process for stents used in surgical procedures, an uncut blank tube (6) is positioned on a core (5) tube which provides both physical support and conducts a fluid cooling medium. The core (5) is held in a spindle (1) which is rotated in steps. When the spindle is stopped, a laser (8) beam (9) cuts apertures (7) in the blank (6) according to a pre-determined pattern.
