1. An apparatus comprising:
a left-ventricular assist device configured to assist left-ventricular functioning of a subject, the left-ventricular assist device comprising:
a tube configured to traverse an aortic valve of the subject, such that a proximal portion of the tube is disposed within an aorta of the subject and a distal portion of the tube is disposed within a left ventricle of the subject, the tube defining at least one blood inlet opening that is configured to be disposed within the subject's left ventricle, and at least one blood outlet opening that is configured to be disposed within the subject's aorta;
a pump disposed within the tube and configured to pump blood through the tube from the subject's left ventricle to the subject's aorta, by pumping the blood into the tube via the at least one blood inlet opening and by pumping blood out of the tube via the at least one blood outlet opening; and
a distal-tip element configured to define a straight proximal portion, and a curved distal portion shaped to define first and second curves with an elongated straight portion between the first and second curves, such that the curved distal portion is effective to center the distal-tip element with respect to the subject's aortic valve.
