    Abstract: Methods for estimating flow rate in a blood circulation assist system employ impeller eccentricity. A method includes magnetically rotating an impeller within a blood flow channel of a blood pump. The impeller is levitated within the blood flow channel transverse to the impeller axis of rotation. A rotational speed for the impeller is determined. At least one impeller transverse position parameter is determined. The at least one impeller transverse position parameter is based on at least one of (1) an amount of a bearing current that is used to levitate the impeller transverse to the impeller axis of rotation, and (2) a position of the impeller within the blood flow channel transverse to the impeller axis of rotation. A flow rate of blood pumped by the blood pump is estimated based on the impeller rotational speed and the at least one impeller transverse position parameter.

    Abstract: The invention is a heart assist device which has been developed in order to maintain the blood circulation in end-stage heart patients who do not respond to medical treatment, and it has been designed in size and shape so that it can be installed into the anatomically spacious root sections of the aorta and main pulmonary artery with its small volume, and exceptional motor design without a shaft, the device, which contains a brushless, asynchronous and three-phase electric motor, will consume much less energy. The three-phase current required for the motor is provided from the power supply outside the body through the synchronous and wireless transmission of three phases. The invention is about a permanent endovascular cardiac support device which contains a three-phase, brushless, asynchronous electric motor, and the required energy is provided through the three-phase wireless power transmission from outside the body.
