摘要： A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.
