摘要

System for generating the pulsatile flow of physiological form associated with ventricular assist devices axial flow and centrifugal in synchrony with the native heart.This is a device that will bring the pulsatile flow back, more physiological, in sync with the native heart and keeping the progress achieved through the continuous flow pumps are the generators of the flow of smaller size.This will be achieved by the union of the technology of biosensors and ventricular assist devices, and creating an interface between them with specific commands of sense and variable rotation.This generator is then composed of ventricular assistance device (1); electronic receipt of cardiac signal and shooting variation of rotation (2); biossensor (3) and (4) forming an injector device assembly that will provide a better circulatory assistance on GA permanence for the generation of pulsatile flow through the response of rotation in synchrony with the heartbeat NAT.Ivo.
