Structural design of an endovascular stent for treatment of an aortic aneurysm
The current models of endovascular stents havean auto-expanding biomechanism with shape memory materialwhich is able to adjust itself in the middle of implantation.These models have problems in implantation procedures in theartery; including problems of decoupling.

Structural design of an endovascular stent for treatment of an aortic aneurysmDiseño estructural de un stent endovascular para el tratamiento de un aneurisma aórticoDesenho estrutural de um stent endovascular para o tratamento de um aneurisma da aortaThe current models of endovascular stents havean auto-expanding biomechanism with shape memory materialwhich is able to adjust itself in the middle of implantation.These models have problems in implantation procedures in theartery; including problems of decoupling. As an alternative tothe situation, a new aortic adjustable stent was developed. Thismodel of controlled mobility aims to facilitate the implantationprocedure and the non-decoupling due to the hemodynamicactivity. A geometric design was developed, and severalsimulations were developed to analyze its biomechanicalbehavior using the Working Model program as a computationaltool. Some results were obtained that indicated the feasibilityand correct functionality of this alternative for the problem ofdecoupling and implantation.Los actuales modelos de stents endovascularestienen un biomecanismo auto-expandible con memoria de formadel material, lo que en principio pretenden es un ajuste adecuadocon el medio de implantación arterial. Sin embargo, presentanalgunos problemas de desacoplamiento y de implantación enla arteria por diversas variabilidades biológicas. Como unaalternativa a estas situaciones, se desarrolló un modelo destent aórtico regulable (ajustable). Este modelo de movilidadcontrolada pretende facilitar el procedimiento de implantación yel no desacoplamiento por la actividad hemodinámica. Se elaboróun diseño geométrico y se desarrollaron diversas simulacionespara analizar su comportamiento biomecánico utilizando comoherramienta computacional el programa Working Model. Seobtuvieron unos resultados que indicaron la viabilidad y correctafuncionalidad de esta alternativa para el problema del desacoplee implantación.Os modelos atuais de stents endovascularestêm um biomecanismo auto-expansível com memória deforma do material, que em princípio se destina a ser um ajusteadequado com os meios de implantação arterial.
