Abstract: A percutaneous lead assembly for an active implantable device, the lead assembly comprising a sheath with a plurality of wires extending from a proximal end to a distal end. The wires being adapted to power the active implantable device; the distal end having at least one electrode fixed thereon. The electrodes being in communication with sensor electronics and wherein at least one electrode is on the outer layer of the lead assembly in which the electrode is used to detect at least one of acceleration and electrical signals of an organ.

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.
