Abstract
Blood pump devices having one or more sensors for monitoring performance of a bearing assembly and/or a fluid-tight seal are provided herein. Such devices are particularly useful in blood pump devices that have cantilevered rotors supported by a sealed mechanical bearing disposed outside a blood flow path of the device to avoid thrombus formation caused by blood contact with the bearing. The one or more sensors can include one or more accelerometers adapted to detect movement of the bearing assembly along one or more axes during operation of the pump. A vibration profile can be determined from the movement data from the one or more sensors that is indicative of performance of the bearing assembly and/or seal so as to allow monitoring over time.
