Abstract
Disclosed are apparatus and methods for measuring pressure and/or flow in blood circulatory systems of a patient using cardiac assist devices. By way of example, a left ventricular assist device may be coupled between the left ventricle of the patient's heart and the aorta. One or more sensors, such as pressure sensors, are located at one or more selected locations in the heart, in blood-carrying conduits that are coupled to the cardiac assist device, or in the aorta, that sense pressure, for example, to monitor a patient's cardiac function. A monitoring device is coupled to the sensors that implements an algorithm that determines pressure and/or blood flow rate in the circulatory system using pressures and/or flow data derived from the sensors.
