Width Error Analysis of Stent Strut and Optimization of Laser Cutting Procedure

  • Received Date: 07 Jul 2006

  • To solve the problem of uneven strut widths of stents cut by laser, laser cutting procedure test was conducted, and the motion of the tube was analyzed.The results show that the deviation of the strut width is mainly caused by the variation in laser defocus and that in the tangent velocity at the cutting point.The procedure parameters were optimized according to the above analysis.The strut widths of the stent cut with the optimized procedure vary within 0.010 mm, conforming to the design specifications, when the eccentricity of tube at cutting point is within 0.030 mm and the defocus is-0.05 mm.
