Dispositivo de assistência circulatória mecânica intraventricular de fluxo axial: estudo in vitro

Biocompatibility of Ricinus comunnis polymer compared to titanium implant used in artificial hearts. Experimental study in guinea pigs

“…We perform tests "in vitro" [2] and idealized device constructed from titanium, and the vast majority of the equipment available in the world. Tests "in vivo" experiments were carried out on sheep and proved the effectiveness of the device [2].…”

“…We perform tests "in vitro" [2] and idealized device constructed from titanium, and the vast majority of the equipment available in the world. Tests "in vivo" experiments were carried out on sheep and proved the effectiveness of the device [2]. Within our main objective, which is the development of national equipment, adapted to the resources of our country, we are in the process of replacing high-cost mechanical parts for substitutes acquired nationally and therefore at lower costs.…”

Bomba sangüínea espiral: concepção, desenvolvimento e aplicação clínica de projeto original

“…The axial principle of flow and pressure is generated through a cylindrical blade arranged spirally around a rotary axis [15,16]. It is admittedly more traumatic due to the high rates of shear stresses imposed to the blood-formed elements established by the spirals and the negative pressure caused when there are blade intervals along the axis [17].…”

“…Nas pesquisas "in vivo" experimentais em ovinos em CEC por 6 horas a BE foi capaz de manter parâmetros pressóricos adequados e Hemoglobina Livre entre 16 (c). Again, despite the advances observed, the tests with these models and the modifications done, the outcomes were not the expected ones.…”

Estudo experimental da aplicação do ventrículo artificial eletromecânico pulsátil implantável

“…Dante Pazzanese Institute of Cardiology (IDPC-SP) also concluded a spiral blood pump project [5,6] and Kubrusly et al [7] published an article on intraventricular assist device of axial flow, which still was in experimental phase.…”
