Frontiers in Neurology, 2021 Background: Wingspan stent has gained interest for better long-term outcomes for intracranial atherosclerosis disease (ICAD). However, in-stent restenosis still presents as a problem and may cause postoperative neurological events. We aimed to find a way

In Silico Fatigue Optimization of TAVR Stent Designs with Physiological Motion in a Beating Heart Model [PDF]
arXiv, 2023 The rapid expansion of TAVR to younger, low-risk patients raises concerns regarding device durability. Necessarily, extended stent lifetime will become more critical for new generation devices. In vitro methods commonly used for TAVR stent fatigue testing exclude the effects of the beating heart.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal

Deformation Mechanics of Self-expanding Venous Stents: Modelling and Experiments [PDF]
arXiv, 2021 Deformation properties of venous stents based on braided design, chevron design, Z design, and diamond design are compared using in vitro experiments coupled with analytical and finite element modelling. Their suitability for deployment in different clinical contexts is assessed based on their deformation characteristics. Self-expanding stainless steel

Calcified in-stent restenosis in a venous stent [PDF]
Journal of Vascular Surgery Cases, 2015 Stenting of the iliac veins has been an established treatment for improving venous runoff from the legs after thrombolysis of iliofemoral deep venous thrombosis for more than a decade, yet little is known about the long-term fate of stents in the central veins. We describe a case of heavily calcified in-stent restenosis in a 10-year-old venous stent as

Stent thrombosis in randomized clinical trials of drug-eluting stents.
New England Journal of Medicine, 2007 BACKGROUND Definitions of stent thrombosis that have been used in clinical trials of drug-eluting stents have been restrictive and have not been used in a uniform manner.

Journal of the American Medical Association (JAMA), 2015 IMPORTANCE Intracranial stenosis is one of the most common etiologies of stroke. To our knowledge, no randomized clinical trials have compared balloon-expandable stent treatment with medical therapy in symptomatic intracranial arterial stenosis ...
