Abstract: Apparatus and methods are described including an axial shaft configured for insertion into, and rotation within, a ventricle of a heart of a subject. An impeller is coupled to the axial shaft and a frame surrounds the impeller. A pump-outlet tube surrounds the frame such that, as the axial shaft rotates, the impeller pumps blood proximally, from the ventricle, through the pump-outlet tube. A flat inlet guard, which is shaped to define one or more holes, is disposed around, and perpendicular to, the axial shaft and within the frame distally to the impeller, such that the blood flows to the impeller via the holes. Other applications are also described.

Abstract: Apparatus and methods are described including a left-ventricular assist device, that includes a collapsible pump-outlet tube configured for insertion, through an aorta of a subject, into a left ventricle of a heart of the subject such that the pump-outlet tube traverses an aortic valve of the subject. The device includes one or more bands, each of which is bonded to an outer wall of the proximal portion of the pump-outlet tube, without extending around a full circumference of the pump-outlet tube, such that, while the proximal portion of the pump-outlet tube is maintained in the open state, the proximal portion of the pump-outlet tube curves at respective locations of the bands. Other applications are also described.

Abstract: Apparatus and methods are described including a left-ventricular assist device that includes a pump-outlet tube shaped to define one or more blood-outlet openings and configured for insertion into a subject's left ventricle, such that the blood-outlet openings are disposed within the subject's aorta and a distal portion of the pump-outlet tube is disposed within the left ventricle. An impeller is disposed within the pump-outlet tube and is configured to pump blood of the subject proximally through the pump-outlet tube. A delivery tube extends from outside the subject's body to the distal portion of the pump-outlet tube. An expandable element surrounds the delivery tube proximally to the blood-outlet openings, a length of the delivery tube between the expandable element and the blood-outlet openings being less than 30 mm. Other applications are also described.
