Abstract: Apparatus and methods are described for use with a venous system of a subject that includes one or more tributary vessels that flow into a vein at junctions. A blood-pump-catheter includes a material configured to be placed at a downstream location that is downstream of the junctions and to at least partially occlude blood flow through the vein. The material defines a blood-outlet opening. A blood pump pumps blood from a region of the vein that is adjacent to the junctions, and through the blood-outlet opening. A blood-flow pathway directs upstream venous blood flow from an upstream location that is upstream of the junctions, to downstream of the material, without the upstream venous blood flow being pumped by the pump. Other applications are also described.

Abstract: Apparatus and methods are described including a ventricular assist device that includes an axial shaft and an impeller disposed on the axial shaft, the impeller being configured to pump blood. A frame is disposed around the impeller. The distal end of the axial shaft is configured to engage with a distal thrust bearing such as to prevent the axial shaft from undergoing axial motion in response to variations in the pressure gradient against which the impeller pumps blood. An impeller-stabilizing spring is disposed around the axial shaft between a distal end of the impeller and the thrust bearing, the impeller-stabilizing spring being configured to stabilize the distal end of the impeller. Other applications are also described.

Abstract: Apparatus and methods are described including a ventricular assist device that includes an impeller configured to be placed inside a subject's left ventricle. A frame is disposed around the impeller, the frame defining generally-cylindrical central portion, and a proximal conical portion that widens from a proximal end of the frame to a proximal end of the generally-cylindrical central portion. A motor drives the impeller to pump blood from the left ventricle to the subject's aorta, by rotation of the impeller. The impeller is configured to be disposed at least partially within the proximal conical portion of the frame during at least some of a time during which the impeller rotates. Other applications are also described.

Abstract: Apparatus and methods are described including manufacturing an impeller by forming a structure having first and second bushings at proximal and distal ends that are connected to one another by at least one elongate element. The elongate element is made to radially expand and form a helical elongate element. An elastomeric material is coupled to the helical elongate element, such that the helical elongate element with the elastomeric material coupled thereto defines a blade of the impeller. The coupling is performed such that a layer of the material disposed around a radially outer edge of the helical elongate element forms the effective edge of the impeller blade. A step is performed to enhance bonding of the elastomeric material to the helical elongate element in a manner that does not cause a protrusion from the effective edge of the impeller blade. Other applications are also described.
