Estudos de técnicas de texturização e biolização, e desempenho biológico in vitro e in vivo em membrana para um dispositivo de assistência ventricular e coração artificial totalmente implantáveis

Estudo experimental da aplicação do ventrículo artificial eletromecânico pulsátil implantável

“…The resulting device is originated from ejection alternating two diaphragms situated in two pumping chambers and its movements performed by brushless motor, controlled by an electronic controller with rechargeable batteries and can be used as an auxiliary to the left ventricle (LV) for both ventricles, even as artificial heart entirely replacing the native organ. In the contractile chamber input and output, two bovine pericardial bioprosthesis were positioned (25 mm and 23 mm) to make the flow become unidirectional, relieving the native ventricular output and providing adequate blood volume which may vary depending on preload alterations or ventricular filling pressure [11][12][13] (Figures 1 and 2).…”
