Influence of Laser Cutting on the Functional Safety of Metallic Vascular Stents

A new method for the determination of missing data from scientific publications were presented on stent cutting lasers, using a combination of computational methods available from different sources in the literature. Some of the setting parameters for pulsed laser cutting are not independent of each other, which gives the possibility to determine some missing data in scientific articles: this way, data from different articles can be better evaluated, compared and experiments can be repeated, which is a useful basis for further development of a manufacturing technology. For this purpose, a new method was developed that allows the determination and calculation of the entire parameter system required for laser stent cutting. Finally, an evaluation system including weighting factors has been developed to quantify the defects of laser stent cutting, to classify the functional safety of the product, and to calculate the missing dimension that characterizes the cutting quality of stent manufacturing.
