    Abstract: Apparatus and methods are described including a blood pump catheter that includes an axial shaft, and an impeller disposed on the axial shaft. A motor drives the impeller to pump blood, by rotating the impeller. A drive cable extends from the motor to the axial shaft, the drive cable being configured to impart rotational motion from the motor to the impeller by rotating. A distal tip portion is disposed at a distal end of the blood pump catheter. The drive cable, the axial shaft, and the distal tip portion define a continuous lumen therethrough from outside the subject's body to the distal end of the blood pump catheter. The continuous lumen facilitates insertion of the blood pump catheter into the subject's body over a guidewire, and, subsequently, provides a channel through which the purging fluid flows. Other applications are also described.

    Abstract: Apparatus and methods are described, including a blood pump that includes a catheter, a proximal impeller disposed on the catheter inside a proximal impeller housing, and which is configured to pump blood by rotating inside the proximal impeller housing. A distal impeller is disposed on the catheter inside a distal impeller housing, distally to the proximal impeller, and the distal impeller is configured to pump blood by rotating inside the distal impeller housing. A tubular element is disposed between the proximal impeller housing and the distal impeller housing, the tubular element being configured to have a tubular configuration during rotation of the proximal and distal impellers. Other applications are also described.

    Abstract: Apparatus and methods are described for improving renal function of a patient, including mechanically occluding the patient's inferior vena cava downstream of the renal vein ostium to form an upstream region and a downstream region of the inferior vena cava, and mechanically pumping blood through the inferior vena cava from the upstream region to a discharge location in the downstream region while the inferior vena cava is occluded, wherein the blood remains in the inferior vena cava while being mechanically pumped. Other applications are also described.

    Abstract: Apparatus and method are described including identifying a subject as suffering from a condition that causes the subject to have elevated central venous pressure. In response thereto, a device is placed inside the subject's vena cava such that an upstream end of the device is placed at a location upstream of junctions of the vena cava with all of the subject's renal veins. The device defines a passage through the device, at least a portion of the passage converging in a direction from an upstream end of the device to downstream end of the device. Other applications are also described.

    Abstract: Apparatus and methods are described including identifying a subject as suffering from a condition selected from the group consisting of: cardiac dysfunction, congestive heart failure, reduced renal blood flow, increased renal vascular resistance, arterial hypertension, and kidney dysfunction. In response thereto, blood pressure within a renal vein of the subject is reduced, by placing a blood pump inside the subject's renal vein and activating the impeller to pump blood from the renal vein into the subject's vena cava. Other applications are also described.

    Abstract: Apparatus and methods are described including identifying a subject as suffering from a condition selected from the group consisting of: cardiac dysfunction, congestive heart failure, reduced renal blood flow, increased renal vascular resistance, arterial hypertension, and kidney dysfunction. In response thereto, blood pressure within a renal vein (32) of the subject is reduced, by placing a blood pump (150) inside the subject's renal vein and activating the impeller to pump blood from the renal vein into the subject's vena cava (26). Other applications are also described.
