Claims14
A system for removing stent islands from a laser cut tube comprising:
- a tube including at least one hole having an opening in an outer surface that is in fluid communication with an interior of the tube;
- a stent positioned over the tube, wherein the stent comprises a scaffolding including a pattern of interconnecting struts formed by laser cutting the pattern into a second tube, wherein the stent comprises a stent island, the island being pieces or portions of material of the second tube that are not intended to be part of the pattern that remain attached to the struts of the stent after the laser cutting;
- and
- a high pressure gas source connected to the tube to supply a compressed gas to the interior of the tube, wherein when the high pressure gas source supplies the compressed gas to the interior of the tube, the compressed gas exits the tube through the at least one hole and facilitates removal of the island.
