Abstract
A polymeric tube is positioned on a polymeric mandrel and then laser cut to form an implantable medical device, such as a stent. The assembly and method reduces contamination of the inner surface of the stent, which would be caused if conventional glass or metal mandrels are used, while simultaneously reducing damage to the inner surface of the stent due to the shielding effect of the polymeric mandrel.
