Abstract: Apparatus and methods are described including a ventricular assist device that includes a blood pump configured to be placed inside a left ventricle of a subject and to pump blood from the subject's left ventricle to an aorta of the subject. A blood pressure sensor measures aortic pressure of the subject. A computer processor varies a flow rate that is that is generated by the blood pump, and determines a relationship between arterial pulsatility of the subject and the flow rate that is generated by the blood pump, based upon aortic pressure that is measured by the blood pressure sensor as the flow rate that is generated by the blood pump is varied. The computer processor estimates native cardiac output of the subject at least partially based upon the relationship. Other applications are also described.

Abstract: Apparatus and methods are described including a ventricular assist device configured to assist ventricular functioning of a subject. The ventricular assist device includes an impeller and a frame disposed around the impeller. An axial shaft extends from a proximal end of the frame to a distal end of the frame, the impeller being coupled to the axial shaft. The axial shaft includes a proximal portion and a distal portion, which are coupled to each other via a joint. The proximal portion and the distal portion of the axial shaft are configured to flex with respect to each other via the joint. Other applications are also described.
