Abstract: Apparatus and methods are described including a catheter (20), a first pump (24U) disposed on the catheter, and a second pump (24D) disposed on the catheter, proximally to the first pump. A control unit (52) is configured to control activation of the first and second pumps. The first and second pumps are configured, when activated, to pump fluid in opposite directions from one another. Other applications are also described.

Abstract: Apparatus and methods are described including a blood pump (24) configured to be placed inside a blood vessel of a in subject, the blood pump including an impeller (28) configured to pump blood by rotating. A support cage (254) is shaped to define a narrow portion (256) that is configured to be disposed around the impeller, and to maintain a separation between a wall of the blood vessel and the impeller, and a radial extension (258) from the narrow portion of the support cage that extends radially outward with respect to the narrow portion of the support cage, the radial extension being configured to substantially maintain a longitudinal axis of the impeller in alignment with a local longitudinal axis of the blood vessel by contacting the wall of the blood vessel. Other applications are also described.

Abstract: Apparatus and methods are described for use with a tributary vessel of a subject that supplies a vein of the subject. Blood within the tributary vessel is mechanically isolated into a compartment that is separated from blood within the vein. Blood flow from the tributary vessel to the vein is controlled by pumping blood from the compartment to the vein. Other applications are also described.

Abstract: Apparatus and methods are described including an impeller that includes an impeller frame that comprises proximal and distal end portions and at least one helical elongate element that winds from the proximal end portion to the distal end portion. A material is coupled to the at least one helical elongate element, such that the at least one helical elongate element with the material coupled thereto defines a blade of the impeller. A plurality of sutures are tied around the at least one helical elongate element, the sutures being configured to facilitate coupling of the material to the at least one helical elongate element. Other applications are also described.

Abstract: Apparatus and methods are described including a tube configured to traverse a subject's aortic valve. A frame is disposed within a portion of the tube, and an impeller is disposed inside the tube such that, when the impeller and the tube are deployed inside the subject, a gap between an outer edge of the impeller and an inner surface of the tube is less than 1 mm. The impeller rotates such as to pump blood from the left ventricle to the aorta, and is stabilized with respect to the tube, such that, during rotation of the impeller, the gap between the outer edge of the impeller and the inner surface of the tube is maintained. The impeller includes at least one impeller blade defined by a helical elongate element, and a film of material supported by the helical elongate element. Other applications are also described.

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.
