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.

Methods for laser cutting tubing to make medical devices

An intraluminal grafting system having a balloon catheter assembly, a capsule catheter assembly and capsule jacket assembly is used for deploying a graft having attachment means in the vessel of an animal body. The system contains a proximal capsule means and a distal capsule means, wherein the graft is disposed within the two capsule means and a removable sheath covers the graft and capsule means. The graft is comprised of a tubular member having superior and inferior ends, having attachment means with wall engaging members secured thereto. The balloon catheter is disposed within the capsule catheter to provide relative movement between the balloon catheter and the capsule catheter, whereby the graft can be removed from the capsule means. The balloon is inflated to firmly implant the graft and attachment means within the vessel. The graft and attachment means remain in the vessel after the intraluminal grafting system is withdrawn.
