Abstract
An improved method of cutting a pattern in a hollow, tubular workpiece to form a stent or the like involves the use of a novel workpiece fixture. The workpiece fixture is rigidly carried on a laser cutting tool to support a long piece of stock tubing in a cantilever manner beneath the laser beam of the cutting tool. The fixture is spaced from the laser beam by a distance which is in a range of approximately the same as to slightly greater than the length of any axial repeat in the pattern. The laser beam cuts the pattern in the stock tubing piece as the stock tubing is advanced past the laser beam. Accuracy is increased because the workpiece fixture is carried on the laser cutting tool, and because the cutting takes place in a zone that is close to the end of the fixture and the cantilever support provided thereby.
