Comparison of dry and wet fibre laser precision cutting for coronary stent manufacture
(Laser Institute of America, 2010)High precision laser micromachining is extensively used in medical device industry. In medical stent fabrication, the processed stents must exhibit mechanically robust structures and high surface quality. High cost of post ... -
Picosecond laser fabrication of nitinol for coronary stent applications
(Laser Institute of America, 2010)Nitinol (a shape memory nickel-titanium alloy) is one of the desirable materials for medical stents applications, due to its high corrosion resistance, self-expansion and biocompatibility. The stents are commonly fabricated ... -
Picosecond laser micromachining of nitinol and platinum-iridium alloy for coronary stent applications
(Springer-Verlag, 2012-03)The demand for micromachining of coronary stents by means of industrial lasers rises quickly for treating coronary artery diseases, which cause more than one million deaths each year. The most widely used types of laser ... -
Three-phase 3D modelling of a laser cutting process using Smoothed Particle Hydrodynamics (SPH)
(Laser Institute of America, 2012)Smoothed Particle Hydrodynamics (SPH) is used to develop a numerical model to simulate the three-phase laser cutting process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ... -
Understanding the behaviour of pulsed laser dry and wet micromachining processes by multi-phase smoothed particle hydrodynamics (SPH) modelling
(IOP Publishing, 2013-03)A smoothed particle hydrodynamics (SPH) numerical model is developed to simulate the three-phase laser micro-machining process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ... -
Underwater femtosecond laser micromachining of thin nitinol tubes for medical coronary stent manufacture
(Springer-Verlag, 2012-06)Microprofiling of medical coronary stents has been dominated by the use of Nd:YAG lasers with pulse lengths in the range of a few milliseconds, and material removal is based on the melt ejection with a high-pressure gas. ...
