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 ...
Comparison of dry and wet fibre laser profile cutting of thin 316L stainless steel tubes for medical device applications
(Elsevier B.V., 2010-11-19)
In medical coronary stent fabrication, high precision profile cutting with minimum post-processing is desirable. Existing methods of profiling thin tubular metallic materials are based mainly on the use of Nd:YAG lasers. ...
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 ...
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 ...
Laser cutting of coronary stents: Progress and development in laser based stent cutting technology
(Trans Tech Publications Ltd., 2015)
Laser cutting is one of the key fabrication technologies applied to coronary stent manufacture. This paper reviews the recent progress in laser-based stent manufacturing, including different type of lasers used, laser ...
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. ...
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 ...
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 ...
