A Fast Method of Virtual Stent Graft Deployment for Computer Assisted EVAR [PDF]
Computational Biomechanics for Medicine, Springer International
Publishing, pp.147-169, 2020, 2021 In this paper we introduce a new method simulating stent graft deployment for assisting endovascular repair of abdominal aortic aneurysms. The method relies on intraoperative images coupled with mechanical models. A multi-step algorithm has been developed to increase the reliability of simulations.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background Premature discontinuation of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is related to higher short‐term risks of adverse outcomes. Whether these risks persist in the long‐term is uncertain. Methods and Results We

In silico modeling for personalized stenting in aortic coarctation [PDF]
Engineering Applications of Computational Fluid Mechanics, 2022,
16: 2056-2073, 2022 Stent intervention is a recommended therapy to reduce the pressure gradient and restore blood flow for patients with coarctation of the aorta (CoA). In this work, we developed a framework for personalized stent intervention in CoA using in silico modeling, combining computational fluid dynamics (CFD) and image-based prediction of the geometry of the ...

Microscale stress-geometry interactions in an additively manufactured NiTi cardiovascular stent: A synchrotron dual imaging tomography and diffraction study [PDF]
Materials Characterization 213 (2024) 114016, 2023 This study explores cardiovascular stents fabricated using laser powder bed fusion (LPBF); an emerging method to offer patient-specific customisable parts. Here, the shape memory alloy NiTi, in a near equiatomic composition, was investigated to deconvolve the material response from macroscopic component effects.

A Synopsis of Stent Graft Technology Development [PDF]
arXiv, 2023 Coronary artery disease (CAD) is a leading cause of death worldwide. Treatments have evolved, with stenting becoming the primary approach over bypass surgery. This article reviews the evolution of coronary stent technology, starting from the first angioplasty in 1977. Pioneers like Forssmann, Dotter, and Gruentzig established the foundation.
