Ventricular assist device

Abstract

Apparatus and methods are described including a left-ventricular assist device (20) that includes a tube (24) configured to traverse a subject's aortic valve, with a distal portion of the tube disposed within the subject's left ventricle. A frame (34) is disposed within the 5 distal portion of the tube. A pump (50) disposed within the frame pumps blood through the tube. A distal-tip element (107) defines a straight proximal portion (346) that defines a longitudinal axis (348), and a curved distal portion that is shaped such as to curve in a first direction with respect to the longitudinal axis before passing through an inflection point and curving in a second direction with respect to the longitudinal axis (348), such that the curved 10 distal portion defines a bulge (351) on one side of the longitudinal axis (348). Other applications are also described.20 26 20 79 51 21 J ul 2 02 6 A B S T R A C T 2 0 2 6 2 0 7 9 5 1 2 1 J u l 2 0 2 6
