Abstract: Apparatus and methods are described including a solid axial shaft having a shaft diameter that is less than 0.8 mm, an impeller configured for insertion into a left ventricle of a heart of a subject and coupled to the axial shaft, and a hollow drive cable coupled, at a distal end of the drive cable, to the axial shaft, and configured to rotate so as to rotate the axial shaft, thereby causing the impeller to pump blood of the subject from the left ventricle. 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, which includes a proximal bushing disposed over the axial shaft, a distal bushing disposed over the axial shaft distally from the proximal bushing, and one or more blades. Each of the blades includes a single inner helical elongate element, a single outer helical elongate element, and a film of material extending between the inner helical elongate element and the outer helical elongate element. The blades are proximally coupled to the proximal bushing and distally coupled to the distal bushing such that, as the axial shaft rotates, the blades rotate, thereby pumping blood of the subject. Other applications are also described.

Abstract: Apparatus and methods are described including a device configured for insertion into a left ventricle of a heart of a subject. A delivery tube is coupled to the device and configured to traverse an aortic arch of the subject while the device is within the left ventricle. An elongation-resistant fiber runs axially along the delivery tube so as to bias an orientation of the delivery tube while the delivery tube traverses the aortic arch such that the elongation-resistant fiber is disposed inside a curve of the aortic arch, thereby biasing an orientation of the device. Other applications are also described.

Abstract: Apparatus and methods are provided, including inserting a drive-cable-bearing tube, which includes one or more inwardly-facing ceramic portions, into a body of a subject and through an aorta of the subject, such that the inwardly-facing ceramic portions are within an aortic arch of the subject, while a drive cable, which is coupled to an intracorporeal device at a distal end of the drive-cable-bearing tube and includes one or more outwardly-facing ceramic portions, passes through the drive-cable-bearing tube such that the outwardly-facing ceramic portions are aligned with the inwardly-facing ceramic portions. The drive cable is rotated within the drive-cable-bearing tube, thereby rotating the intracorporeal device, while the outwardly-facing ceramic portions are aligned with the inwardly-facing ceramic portions. Other applications are also described.

Abstract: Apparatus and methods are described including identifying a subject as suffering from cardiac dysfunction, congestive heart failure, reduced renal blood flow, increased renal vascular resistance, arterial hypertension, and/or kidney dysfunction, and, in response thereto, reducing blood pressure within a renal vein of the subject, by activating at least one impeller to pump blood from the renal vein into a vena cava of the subject, by the impeller rotating.

Abstract: Apparatus and methods are described including inserting a catheter into a subject's body via a vein of the subject's groin. The catheter is advanced distally such that a distal end of the catheter is disposed inside the subject's renal vein. Respective stabilizing portions of the catheter stabilize the catheter by being in contact with inner walls of, respectively, an iliac vein of the subject, and a vena cava of the subject. Subsequently, a medical device is deployed inside the renal vein by retracting the distal end of the catheter, such that the distal end of the catheter is in a retracted state, in which the respective stabilizing portions of the catheter still stabilize the catheter by being in contact with the inner walls of, respectively, the subject's iliac vein and the subject's vena cava. Other applications are also described.

Abstract: Apparatus and methods are described including reducing cardiac preload of a subject by partially occluding a vena cava of the subject at an infra-renal location. One or more physiological parameters of the subject are monitored, the one or more physiological parameters including lower body venous pressure, central venous pressure, central venous blood flow, renal venous pressure, cardiac diameter, cardiac volume, arterial pressure, and/or arterial blood flow. An extent to which the vena cava is occluded at the infra-renal location is modulated, responsively to the one or more physiological parameters. Other applications are also described.

Abstract: Apparatus and methods are described including a blood pump including an axial shaft configured for insertion into, and rotation within, a body of a subject, and an impeller coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. A frame surrounds the impeller. One or more steering wires are coupled to the frame and configured to extend from the frame, to outside the body of the subject, while the frame is within the body. Other applications are also described.
