CFD-based comparison study of a new flow diverting stent and commercially-available ones for the treatment of cerebral aneurysms
Flow-diverting stents (FDSs) show considerable promise for the treatment of cerebral aneurysms by diverting blood flow away from the aneurysmal sacs, however, post-treatment complications such as failure of occlusion and ... -
Computational simulation of scleral buckling surgery for rhegmatogenous retinal detachment: on the effect of the band size on the myopization
A finite element model (FE) of the eye including cornea, sclera, crystalline lens, and ciliary body was created to analyze the influence of the silicone encircling bandwidth and the tightness degree on the myopia induced ... -
Experimental bench for hemodynamic study of coronary artery with serial stenoses: fractional flow reserve assessment
The aim of this study was to develop an experimental hemodynamic bench to elucidate the influences of such geometrical parameters on the FFR assessment. As a first approach, the present work was focused on the influence ... -
Fluid-structure simulation of a general non-contact tonometry. A required complexity?
Understanding corneal biomechanics is important for applications regarding refractive surgery prediction outcomes and the study of pathologies affecting the cornea itself. In this regard, non-contact tonometry (NCT) is ... -
The hemodynamics of aneurysms treated with flow-diverting stents considering both stent and aneurysm/artery geometries
Flow diverting stents are deployed to reduce the blood flow into the aneurysm, which would thereby induce thrombosis in the aneurysm sac; the stents prevent its rupture. The present study aimed to examine and quantify the ... -
An image-based framework for the analysis of the murine microvasculature: from tissue clarification to computational hemodynamics
The blood–brain barrier is a unique physiological structure acting as a filter for every molecule reaching the brain through the blood. For this reason, an effective pharmacologic treatment supplied to a patient by ... -
In vitro comparison of Günther Tulip and Celect filters. Testing filtering efficiency and pressure drop
In this study, the trapping ability of the Günther Tulip and Celect inferior vena cava filters was evaluated. Thrombus capture rates of the filters were tested in vitro in horizontal position with thrombus diameters of 3 ... -
Influence of a commercial antithrombotic filter on the caval blood flow during neutra and valsalva maneuver
Anticoagulants are the treatment of choice for pulmonary embolism. When these fail or are contraindicated, vena cava filters are effective devices for preventing clots from the legs from migrating to the lung. Many ... -
Modeling the flow and mass transport in a mechanically stimulated parametric porous scaffold under fluid-structure interaction approach
Tissue engineering scaffolds combined with bioreactors are used to cultivate cells with the aim of reproducing tissues and organs. The cultivating process is critical due to the delicate in-vitro environment in which the ... -
Modelling particle transport and deposition in the human healthy and stented tracheobronchial airways
The main goal of this study is the quantification of the particle transport and deposition within the human airways during light, normal and exercise breathing conditions using the computational fluid dynamics. In particular ... -
Nasal anatomy and sniffing in respiration and olfaction of wild and domestic animals
Animals have been widely utilized as surrogate models for humans in exposure testing, infectious disease experiments, and immunology studies. However, respiratory diseases affect both humans and animals. These disorders ... -
Numerical and experimental study of the fluid flow through a medical device
The purpose of this paper is to verify a commercial software based fluid–structure interaction scheme for the inferior vena cava. Vena cava deep thrombosis (TVP) is a potentially deathly disease consequent to pulmonary ... -
On studying the interaction between different stent models and rabbit tracheal tissue: numerical, endoscopic and histological comparison
Stenting technique is employed worldwide for treating atherosclerotic vessel and tracheal stenosis. Both diseases can be treated by means of metallic stents which present advantages but are affected by the main problem of ... -
A parametric model for studying the aorta hemodynamics by means of the computational fluid dynamics
Perturbed aorta hemodynamics, as for the carotid and the coronary artery, has been identified as potential predicting factor for cardiovascular diseases. In this study, we propose a parametric study based on the computational ... -
A parametric tool for studying a new tracheobronchial silicone stent prototype: toward a customized 3d printable prosthesis
The management of complex airway disorders is challenging, as the airway stent placement usually results in several complications. Tissue reaction to the foreign body, poor mechanical properties and inadequate fit of the ... -
Salbutamol transport and deposition in healthy cat airways under different breathing conditions and particle sizes
Salbutamol is a bronchodilatator commonly used for the treatment of feline inflammatory lower airway disease, including asthma or acute bronchospasm. As in humans, a pressurized metered dose inhaler (pMDI) is used in ... -
Salbutamol transport and deposition in the upper and lower airway with different devices in cats: a computational fluid dynamics approach
Pressurized metered-dose inhalers (pMDI) with or without spacers are commonly used for the treatment of feline inflammatory airway disease. During traditional airways treatments, a substantial amount of drugs are wasted ... -
A theoretical model of the endothelial cell morphology due to different waveforms
Endothelial cells are key units in the regulatory biological process of blood vessels. They represent an interface to transmit variations on the fluid dynamic changes. They are able to adapt its cytoskeleton, by means of ... -
Topological features dictate the mechanics of the mammalian brains
Understanding brain mechanics is crucial in the study of pathologies involving brain deformations such as tumor, strokes, or in traumatic brain injury. Apart from the intrinsic mechanical properties of the brain tissue, ... -
Use of computational fluid dynamics to compare upper airway pressures and airflow resistance in brachycephalic, mesocephalic, and dolichocephalic dogs
Brachycephalic dog breeds are prone to breathing difficulties because of their upper airway anatomy. Several surgical techniques exist to correct anatomical pathologies and common surgical approaches aim to correct functional ...
