Simulation of bifurcated stent grafts to treat abdominal aortic aneurysms (AAA) [PDF]
, 2016 In this paper a method is introduced, to visualize bifurcated stent grafts in CT-Data. The aim is to improve therapy planning for minimal invasive treatment of abdominal aortic aneurysms (AAA). Due to precise measurement of the abdominal aortic aneurysm and exact simulation of the bifurcated stent graft, physicians are supported in choosing a suitable ...

A polymer coated cicaprost-eluting stent increases neointima formation and impairs vessel function in the rabbit iliac artery [PDF]
, 2016 Drug-eluting stents have been successful in reducing in-stent restenosis but are not suitable for all lesion types and have been implicated in causing late stent thrombosis due to incomplete regeneration of the endothelial cell layer.

Journal of the American Medical Association (JAMA), 2015 IMPORTANCE Use of intravascular ultrasound (IVUS) promotes better clinical outcomes for coronary intervention in complex coronary lesions. However, randomized data demonstrating the clinical usefulness of IVUS are limited for lesions treated with drug ...

Prediction of stent under-expansion in calcified coronary arteries using machine-learning on intravascular optical coherence tomography [PDF]
arXiv, 2022 BACKGROUND Careful evaluation of the risk of stent under-expansions before the intervention will aid treatment planning, including the application of a pre-stent plaque modification strategy. OBJECTIVES It remains challenging to achieve a proper stent expansion in the presence of severely calcified coronary lesions.

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.

Parametric optimization of the femoropopliteal artery stent design based on numerical analysis [PDF]
, 2021 High-failure rates of Peripheral Arterial Disease (PAD) stenting were reported due to the inability of certain stent strut configuration to accommodate severe biomechanical environment of the Femoro-Popliteal Artery (FPA) such as bends, twists, and ...
