Abstract: Apparatus and methods are provided, including a left-ventricular assist device that includes an impeller configured for insertion into a subject's left ventricle. A delivery tube passes through the subject's aorta, from outside the subject into the left ventricle. The delivery tube includes an outer layer that varies along a length of the delivery tube such that a flexural rigidity of the delivery tube at a first portion of the delivery tube, which is configured to traverse the aortic valve, is less than the flexural rigidity at a second portion, which is configured to traverse at least a portion of the aortic arch, and the flexural rigidity at the second portion is less than the flexural rigidity at a third portion, which is configured to traverse the descending aorta. Other applications are also described.

Abstract: Apparatus and methods are described including a blood pump that includes an axial shaft configured for insertion into, and rotation within, a subject's body. The blood pump also includes an impeller coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. Proximal and distal radial bearings surround the axial shaft and are configured to radially stabilize the axial shaft while the axial shaft rotates. Proximal and distal sleeves, which are less flexible than the axial shaft, are disposed around the axial shaft, such that the proximal and distal sleeves contact the proximal and distal radial bearings, respectively, as the axial shaft rotates. A ratio between a length of the axial shaft and a combined length of the proximal sleeve and distal sleeve is between 2:1 and 6:1. Other applications are also described.

Abstract: Apparatus and methods are provided, including inserting an impeller and a delivery tube into a subject's body, the delivery tube including a braid having a pick density that varies along the delivery tube's length such that a flexural rigidity of the delivery tube at a first portion of the delivery tube is less than the flexural rigidity at a second portion of the delivery tube, and the flexural rigidity at the second portion is less than the flexural rigidity at a third portion of the delivery tube. The impeller and delivery tube are positioned such that the impeller is disposed within the subject's left ventricle and the delivery tube passes the subject's aorta into the left ventricle. Using a drive cable, which passes through the delivery tube, the impeller is rotated so as to pump blood from the left ventricle into the aorta. Other applications are also described.

Abstract: Apparatus and methods are described including a blood pump that includes an axial shaft configured for insertion, over a guidewire, into a subject's body, and for rotation within the subject's body. The axial shaft is shaped to define a shaft lumen for passage of the guidewire therethrough. An impeller is coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. A thrust bearing is disposed distally from the axial shaft so as to inhibit distal movement of the axial shaft beyond the thrust bearing. The thrust bearing is shaped to define a bearing lumen that is configured to be continuous with the shaft lumen. At least a portion of the bearing lumen is frustoconically-shaped, a wider end of the frustoconically-shaped portion of the bearing lumen facing distally. 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 laterally-facing blood-outlet openings and including a first section and a second section that overlap one another between the laterally-facing blood-outlet openings. The pump-outlet tube is 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 with the lateral blood-outlet openings being disposed within the aorta. An impeller is disposed within the first section of the pump-outlet tube and is configured to pump blood of the subject, through the laterally-facing blood-outlet openings, from the left ventricle into the aorta. Other applications are also described.

Abstract: Apparatus and methods are described including inserting a drive-cable end of a drive cable, which includes a plurality of coiled wires, and a hollow-shaft end of a hollow shaft, which hollow-shaft end is shaped to define multiple shaft pores, into opposing ends of a coupling tube, which is shaped to define multiple coupling-tube pores. While the drive-cable end and hollow-shaft end are inside the coupling tube, a molten material is flowed between the coiled wires at the drive-cable end via the coupling-tube pores, and into the hollow-shaft end via the coupling-tube pores and shaft pores, such that, upon solidifying, the material bonds the drive cable to the shaft. Other applications are also described.

A frame surrounds the impeller and a tip portion is coupled to a distal end of the frame. The tip portion includes a distal curved portion, which, when deployed within the left ventricle, lies in a plane, and a proximal curved portion, which, when deployed within the left ventricle, does not lie in the plane and is curved such that, following the insertion of the axial shaft into the left ventricle via an aorta of the subject, a distal end of the proximal curved portion points toward an apex of the left ventricle. Other applications are also described.
