Notes:
Laser cutting error has large influence on the beam width of intravascular stents. Minorrandom variation in beam width of stents may significantly impact the expansion uniformity. In thispaper, the relevant factors that may affect the beam width during the manufacture are investigated.Based on the randomization model, the pattern how the factors affect expansion uniformity isexplored, and the method for calculating uniformity index is proposed. A detailed computation ismade on the width randomization for the two expansion elements. The results show that with theincrease of the value range of beam width, probability of uniformity index decreases gradually; thestrengthening factor has large effect on the expansion uniformity. The method is meaningful forstudying how the processing error affects expansion uniformity
