Abstract
Apparatus and methods are described including a ventricular assist device that includes a tube. A proximal portion of the tube traverses a subject's aortic valve, and a distal portion of the tube is disposed within the subject's left ventricle. A blood pump is disposed within the distal portion of the tube and pumps blood through the tube from the subject's left ventricle to the subject's aorta, by pumping the blood into the tube via one or more blood inlet openings that are defined by the tube and that are configured to be disposed within the subject's left ventricle, and by pumping blood out of the tube via one or more blood outlet openings that are defined by the tube and that are configured to be disposed within the subject's aorta. The one or more blood outlet openings have teardrop shapes. Other applications are also described.
