Mixed formulation of the one-dimensional equilibrium model for elastic stents [PDF]
arXiv, 2017 In this paper we formulate and analyze the mixed formulation of the one-dimensional equilibrium model of elastic stents. The model is based on the curved rod model for the inextensible and ushearable struts and is formulated in the weak form in \v{C}ani\'

Mitigation of the Turbulence within an Arteriovenous Fistula with a Stent Implantation [PDF]
Physical Review Fluids, 7 (2022), 2022 The transitional flow which initiates within the junction (anastomosis) of an arteriovenous fistula (AVF) is known to be a contributing factor in the onset of vascular disease. A novel treatment method involving the implantation of a flexible stent across the anastomosis has enabled the retention of a large proportion of functioning AVFs, despite the ...

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.

Endoscopically Applied Biodegradable Stent in a Rabbit Model of Pediatric Tracheomalacia [PDF]
Clinical and Experimental Otorhinolaryngology, 2021 Objectives A polydioxanone (PDO) stent was developed to treat tracheomalacia in pediatric patients. However, its safety and efficacy need to be verified in animal studies before clinical trials in patients can be conducted.

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 ...
