After crimping and deployment, stents undergo millions of cyclic loads imposed by heart\/neck\/leg movements, causing fatigue failure and device fracture that can lead to possibly severe consequences for the patient. Standard regulations require experimental testing for the preclinical assessment of such devices, which can be coupled with numerical modeling to reduce the time and costs of such campaigns and to obtain more information regarding the local state of stress and strain in the device. In this frame, this review aimed to enlighten the relevant choices that can affect the outcome of the fatigue analysis of Ni-Ti devices, both from experimental and numerical perspectives.<\/jats:p>","DOI":"10.3390\/ma16083178","type":"journal-article","created":{"date-parts":[[2023,4,18]],"date-time":"2023-04-18T02:30:03Z","timestamp":1681785003000},"page":"3178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Relevant Choices Affecting the Fatigue Analysis of Ni-Ti Endovascular Devices"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8621-2503","authenticated-orcid":false,"given":"Francesca","family":"Berti","sequence":"first","affiliation":[{"name":"Department of Chemistry, Materials and Chemical Engineering \u201cG.
