Abstract: An improved expandable stent for implantation in a body lumen, such as an artery, and an improved method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cut cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements, the elements having a rectangular cross-section from cut-to-cut. The individual radially expandable cylindrical elements are disposed in an undulating pattern. The stent is manufactured by direct laser cutting from a single metal tube using a finely focused laser beam originating from a diode pumped fiber laser with an external pulse generator and passing through a coaxial gas jet structure to impinge on the working surface of the tube as the linear and rotary velocity of the tube is precisely controlled. To optimize the cut, the laser parameters may be adjusted and/or the laser pulse may be shaped.

Abstract: The method provides technical nitrogen instead of pure nitrogen in liquid form which has to be heated to be brought in gaseous form for laser cutting. Atmospheric air is compressed and driven through a cascade of high density bundles of hollow membrane fibers to permeate oxygen and air's component gases and yield technical nitrogen, and the pressure of the technical nitrogen is boosted to feed the laser cutting equipment. The method thus improves the laser cutting so as to avoid the drawbacks resulting from use of nitrogen in liquid form obtained by the cryogenic process by using technical nitrogen obtained via the aforesaid hollow fiber membrane technology in an efficient and cost effective manner.

Abstract: A piercing nozzle (2) having a nozzle hole (2a) larger than the diameter of a converged laser beam (10) and smaller than the diameter of a hole (1a) of a cutting nozzle (1) is in use. Further, an underlay (3) having a hole (3a) at a position corresponding to the nozzle hole (2a) is placed under the piercing nozzle (2) through a clearance (5). Piercing is carried out by irradiating the laser beam (10) to a machining target (6) through nozzle holes (1a, 2a) and (3a) on condition that a laser oscillator is set to output high power. The diameter of a hole machined by the piercing is small, and less scattered dross is produced. The scattered dross is cooled down within the clearance (5) and is then dropped down to the underlay (3), so that the adhesion of the scattered dross to the machining target does not occur. Since a small hole is machined with the high power, the machining time for piercing is remarkably shortened.

Abstract: A system for treating surface material overlying a substrate, and more particularly, to a system for ablating contaminates and other unwanted material from a worksite using a pulsed laser beam. The system includes three main sub-systems: a back end (30), a work head (100), and an umbilical tube (88) to protect conduits communicating between the back end (30) and the work head (100). The back end (30) includes heavy and bulky equipment such as a laser (32), chiller, pressurized air source (70), suction system, waste containment system, and electric power source (78). A conveyance such as a trailer may enclose the back end (30) to make it transportable. The work head (100) includes lightweight equipment such as scanning mirrors, optics, and camera (130). During operation, the work head (100) is pressed against the surface material and the laser (32) activated. Then scanning mirrors within the work head (100) arrange pulses from the laser beam according to a selected raster and dither pattern and direct them to the surface material. Ablated detritus may be suctioned through a conduit through the work head (100) and thence to the waste containment system in the back end (30). Electric power, laser energy, control and monitor signals, air, and suction are transported between the back end (30) and the work head (100) through the conduits encased within the umbilical tube (88).
