ARISTIZABAL, S.; SUAREZ, G.  e  PARRA, S.. Structural design of an endovascular stent for treatment of an aortic aneurysm. Entre Ciencia e Ingenieria [online]. 2018, vol.12, n.24, pp.9-14. ISSN 1909-8367.  https://doi.org/10.31908/19098367.3809.

The current models of endovascular stents have an auto-expanding biomechanism with shape memory material which is able to adjust itself in the middle of implantation. These models have problems in implantation procedures in the artery; including problems of decoupling. As an alternative to the situation, a new aortic adjustable stent was developed. This model of controlled mobility aims to facilitate the implantation procedure and the non-decoupling due to the hemodynamic activity. A geometric design was developed, and several simulations were developed to analyze its biomechanical behavior using the Working Model program as a computational tool. Some results were obtained that indicated the feasibility and correct functionality of this alternative for the problem of decoupling and implantation.
