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 thromboembolism (TEP). TEP consist in the obstruction of the pulmonary artery due to a blood clot traveling in the cardiovascular system and is treated with anticoagulants and inferior vena cava filters. Flow fields along the vena cava and an antithrombus filter were studied and compared with a Particle Image Velocimetry (PIV) based model to validate the numerical model. The results show that the fluid–structure interaction (FSI) models are valid and can be used to study the deformations in the inferior vena cava wall using patient-specific geometries

Holografía digital endoscópica para el estudio de la dinámica de sistemas cardiovasculares

Dada la importancia del estudio de las enfermedades cardiovasculares, en este trabajo se propone una técnica no invasiva para medir la velocidad de la sangre en una vena y la deformación de las paredes de la vena. La técnica aplica métodos de holografía digital con un sistema óptico cuyo componente principal es un endoscopio
