Tracheal geometry was obtained from CT images of a healthy man. Then, a computational model of a real human trachea was selected to analyze the deformation of the trachea after implantation of the prosthesis. Finally, it was analyzed under the maximum average static pressure of the entrance to the trachea using the Fluid-Structure Interaction (FSI) approach. A mesh based on unstructured elements for air and structured elements for the tracheal wall was created to perform simulations using ANSYS software.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The deformation of the stent was compared and analyzed with the deformation of the healthy trachea in the absence of the stent. The results presented that the most deformation in the trachea before stenting is up to 8.3\u2009mm. The behavior of SMA2 with a deformation of 5.8\u2009mm was more consistent with the deformation conditions of the trachea for real body conditions without the presence of a stent.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>As much as the deformation is reduced by the degree of stress concentration at the connection point of the stent to the trachea, the risks of stent displacement and patient suffocation are avoided.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11795972251330678","type":"journal-article","created":{"date-parts":[[2025,4,12]],"date-time":"2025-04-12T05:46:46Z","timestamp":1744436806000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Can Smart Alloy Material Improve the Biomechanical Behavior of Prostheses Used in the Human Trachea?
