Abstract

With the established technique of laser in precision micromaterial processing, the fabrication of cardiovascular metallic stent with high quality has now become feasible. From the actual CAD design and FEM analysis of the stent fabrication, the need for the surface modification properties becomes essential in enduring its extended life duration. This paper describes the current status as well as fabrication of such metallic stent of length 20 mm and dia. 2.1 mm with an annular tube thickness of 0.2 mm, by using the short pulse Nd-YAG laser. Fine structures with slit width of 0.1 mm and pitch better than 0.2 mm are created with sharpness and low roughness in the cut surface. Some features on improving the surface characteristics of the cut surfaces of the stent, excimer laser coronary angioplasty and ultrasound ablation of plaque as well as a few techniques on preventing restenosis are well documented.
