Patient-specific simulation of stent-graft deployment within an abdominal aortic aneurysm [PDF]

open access: yes, 2013
In this study, finite element analysis is used to simulate the surgical deployment procedure of a bifurcated stent-graft on a real patient's arterial geometry. The stent-graft is modeled using realistic constitutive properties for both the stent and most

Bioresorbable Scaffold Visualization in IVOCT Images Using CNNs and Weakly Supervised Localization [PDF]

open access: yesarXiv, 2018
Bioresorbable scaffolds have become a popular choice for treatment of coronary heart disease, replacing traditional metal stents. Often, intravascular optical coherence tomography is used to assess potential malapposition after implantation and for follow-up examinations later on.

Endovascular Treatment of Intracranial Atherosclerotic Stenosis: Current Debates and Future Prospects

open access: yesFrontiers in Neurology, 2018
Intracranial atherosclerotic stenosis (ICAS) is a common cause of transient ischemic attack (TIA) and ischemic stroke. Endovascular treatment, including balloon angioplasty alone, balloon-mounted stents, and self-expandable stent placement with or ...

Microfocal X-Ray Computed Tomography Post-Processing Operations for Optimizing Reconstruction Volumes of Stented Arteries During 3D Computational Fluid Dynamics Modeling [PDF]

open access: yes, 2005
Restenosis caused by neointimal hyperplasia (NH) remains an important clinical problem after stent implantation. Restenosis varies with stent geometry, and idealized computational fluid dynamics (CFD) models have indicated that geometric properties of ...

Individual and Domain Adaptation in Sentence Planning for Dialogue

open access: yes, 2011
One of the biggest challenges in the development and deployment of spoken dialogue systems is the design of the spoken language generation module. This challenge arises from the need for the generator to adapt to many features of the dialogue domain ...

Endovascular therapy for chronic cerebrospinal venous insufficiency in multiple sclerosis

open access: yesFrontiers in Neurology, 2011
Recent reports have emerged suggesting that multiple sclerosis (MS) may be due to abnormal venous outflow from the central nervous system, termed Chronic Cerebrospinal Venous Insufficiency (CCSVI).

Degradation modeling of poly-l-lactide acid (PLLA) bioresorbable vascular scaffold within a coronary artery

open access: yesNanotechnology Reviews, 2020
In this work, a strain-based degradation model was implemented and validated to better understand the dynamic interactions between the bioresorbable vascular scaffold (BVS) and the artery during the degradation process.
