The end shape has no influence on the equivalent stress, but has a great influence on the contact stress in the narrowest zone of the oesophagus\u2010neoplasm system. However, the end shapes have significant effect on the equivalent stress and the contact stress in the healthy area of the oesophagus in contact with the stent ends. The results show that the maximum equivalent stress of the oesophagus occurs in the zone contact with the cup\u2010shaped end and the maximum contact stress occurs in the zone contact with the edge of the trumpet\u2010shaped stent end. Moreover, the stent apposition is almost not affected by the end shapes. Although small zones with an incomplete stent apposition appear in the transition zones of spherical\u2010cup\u2010shaped stent, such occurrence might not contribute to stent malapposition or stent migration. Therefore, these stents with 3 types of end shapes all have good stent apposition. Finally, the numerical simulation results can be used to assess the mechanical performance of stents with different end shapes, the effectiveness of stent expansion therapy, and the possibility of complications after stent implantation.<\/jats:p>","DOI":"10.1002\/cnm.2971","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T19:53:52Z","timestamp":1519242832000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Numerical research on the biomechanical behaviour of braided stents with different end shapes and stent\u2010oesophagus interaction"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4807-0652","authenticated-orcid":false,"given":"Xiao\u2010Yu","family":"Ni","sequence":"first","affiliation":[{"name":"School of Mechanical and Electronic Engineering Nanjing Forestry University Nanjing Jiangsu Province 210037 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan\u2010Hong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electronic Engineering Nanjing Forestry University Nanjing Jiangsu Province 210037 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai\u2010Xia","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electronic Engineering Nanjing Forestry University Nanjing Jiangsu Province 210037 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang\u2010Wang","family":"Pan","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory for Design and Manufacture of Micro\/Nano Biomedical Instruments Micro\u2010Tech (Nanjing) Co., Ltd.
