Durability Testing of Stents Using Sensitivity-Based Methods in R
The current industry protocol for durability testing of vascular stents and frames involves testing many implants simultaneously at a range of different stimulus magnitudes (typically strain or stress). The test levels are spread out like a grid across the stimulus range of interest. Each implant is tested to failure or run-out at its specified level and a model is fit to the data using methods similar to those described in Meeker and Escobar.
