Abstract
An implantable device, adapted for assisting the flow of blood from left atrium to an aorta of an in-vivo heart, includes an inlet cannula and an outlet cannula in fluid communication with an implanted blood pressure pump. A first accelerometer is mounted on a housing of the blood pressure pump and is adapted for measuring mitral valve motion. An external controller is in electrical communication with at least one implanted ECG sensor adapted for detecting ECG signals. The at least one implanted ECG sensor is positioned between the implanted blood pressure pump and the external controller. The external controller includes a processor adapted to analyse detected ECG signals and the mitral valve motion. The processor dynamically adjusts a target blood pressure pump speed based on ECG signals and the mitral valve motion such that blood flows from left atrium to left ventricle and then to the aorta.
