The tool includes a tube with at least one exit hole in communication with the interior of the tube, and the tube being connected to a pressurized fluid source. A stent island is located over the exit hole and is removed by the force of the exiting fluid from the exit hole. ## Claims ### Claim 1 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. ### Claim 3 (depends on 1) The system of claim 1, further comprising at least one collet securing the stent to the tube. ### Claim 4 (depends on 1) The system of claim 1, wherein the stent is positioned over the tube with a slip fit that allows for axial and rotational movement of the stent. ### Claim 5 (depends on 1) The system of claim 1, wherein the tube has an outer diameter the same as the inner diameter of the stent. ### Claim 6 (depends on 1) The system of claim 1, wherein one end of the tube is occluded and the other end is connected to the high pressure gas source. ### Claim 7 (depends on 1) The system of claim 1, wherein each end of the tube is occluded and the high pressure gas source is in fluid communication with the interior of the tube through the surface of the tube. ### Claim 8 (depends on 1) The system of claim 1, wherein the tube is attached to a fixture that rotates the tube. ### Claim 9 (depends on 1) The system of claim 1, wherein the holes are arranged in a circumferential pattern around the circumference of the tube. ### Claim 9 (depends on 1) The system of claim 1, wherein the holes are arranged in a helical pattern around the tube. ### Claim 10 (depends on 1) The system of claim 1, wherein the holes are arranged in a pattern along the longitudinal axis of the stent. ### Claim 11 (depends on 1) The system of claim 1, wherein the cross-section of the holes between the inside and outside of the tube increases so that the hole acts to disperse gas flow. ### Claim 12 (depends on 1) The system of claim 1, wherein the cross-section of the holes between the inside and outside of the tube decreases so that the hole acts to concentrate gas flow. ### Claim 13 (depends on 1) The system of claim 1, wherein the scaffolding is made of a bioabsorbable polymer. ### Claim 14 (depends on 1) The system of claim 1, wherein the island is positioned over the hole.
