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 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.
Claims8
A method of manufacturing an implantable medical device, comprising:
- positioning at least one of a polymeric mandrel or polymeric tube relative to the other such that the polymeric mandrel is within the polymeric tube forming a tubing-mandrel assembly, wherein the polymeric tube and the polymeric mandrel are formed from the same bioerodable polymer;
- cutting the polymeric tube while the polymeric mandrel is positioned within the polymeric tube with a laser to form an implantable medical device;
- and removing the implantable medical device from the polymeric mandrel.
