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