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\'{c} and Tamba\v{c}a, 2012.

A novel glycyrrhizin acid-coated stent reduces neointimal formation in a rabbit iliac artery model
Frontiers in Pharmacology, 2023 Introduction: Most drug-eluting stents (DESs) inhibit intimal hyperplasia but impair re-endothelialization. This study aimed to evaluate in vivo strut coverage and neointimal growth in a new glycyrrhizin acid (GA)-eluting stent.Methods: New Zealand White

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 ...
