Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to 'blast' islands from the workpiece.
