摘要: Systems and methods for improving kidney function. A first mechanical circulatory support system (MCS) is introduced in a patient's heart, and a second mechanical circulatory support system is introduced in a patient's inferior vena cava or renal vein. The second mechanical circulatory support system is operated while the first mechanical circulatory support system is operating. A renal parameter is monitored during. Combined operation of the two mechanical circulatory support systems results in a change in renal parameter, e.g. pressure drop in the renal vein, indicating an improvement in kidney function. Once the renal parameter is determined to be below a target threshold, operation of the second mechanical circulatory support device is stopped.

摘要: Apparatus and methods are described including an impeller for use in a blood pump. An impeller frame includes 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 helical elongate element, such that the helical elongate element with the material coupled thereto defines a blade of the impeller. A mediator is coupled to the helical elongate element. The helical elongate element has a first stiffness, the material has a lower stiffness than the first stiffness, and the mediator is configured to enhance bonding between the helical elongate element and the material. Other applications are also described.

摘要: 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.

摘要: System for assisting vascular fluid flow body comprising: Fluid pump having an inlet for fluid in the vascular system to enter and an outlet for discharging pumped fluid into the vascular system at a fluid pump outlet pressure. Occluder placed into the vascular system at a location downstream of the outlet of the fluid pump. Occluder having a configuration in which the occluder occludes the vascular system and a configuration in which pumped is capable of flowing past the occluder. In use, the occluder being actuatable to alternate between the occluded configuration, in which pumped fluid accumulates in the vascular system becoming increasingly under pressure via elastic deformation of vessels, and the flow configuration, in which accumulated pumped fluid under pressure flows past the occluder at a greater pressure than the fluid pump outlet pressure, returning the elastically deformed vessels towards their original state.

摘要: Methods and apparatuses for pumping blood within a blood vessel are described. The methods and apparatuses can be used for renal decongestion by pumping blood through the kidney(s), thereby increasing a pressure gradient across the kidney(s). The apparatuses can include one or more inflatable elements that can be repeatedly inflated and deflated to cause a pumping action within the blood vessel. In some embodiments, the one or more inflatable elements are positioned within one or more stents.

摘要: An aspiration system includes a plurality of catheters located at least partially within the lumen of an outer sheath. The outer sheath and the catheters are configured to slide relative to each other between a first state in which the distal ends of the catheters are located within the lumen of the outer sheath, and a second state in which the distal end and an end length section of each catheter is extended through the distal end of the outer sheath and outside of the lumen of the outer sheath. The end length section of each catheter is configured to spring or flare outward relative to the first state, when the outer sheath and the plurality of catheters are in the second state. The distal end of the outer sheath may be placed in an inferior vena cava or iliac vein in a transplant kidney patient, adjacent at least one renal vein, with the outer sheath and the plurality of catheters in the first state. Then, the system may be transitioned to the second state to cause the end length sections of the catheters to spring or flare outward adjacent the renal vein. The catheters are connected to a suction source for aspiration through the catheter end length sections.

摘要: Apparatus and methods are described including an impeller configured, in a radially-expanded configuration thereof, to pump a fluid by rotating. A radially expandable cage is disposed around the impeller, such that, in radially-expanded configurations of the impeller and the cage, the impeller is separated from an inner surface of the cage. The impeller is disposed within the cage such that, in response to the cage becoming radially contracted and axially elongated, the impeller radially contracts and axially elongates. Other applications are also described.

摘要: A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, and an impeller arranged in said pump casing so as to be rotatable about an axis of rotation. The impeller has blades sized and shaped for conveying blood from the blood flow inlet to the blood flow outlet. The blood pump also has an outflow cannula having an upstream end portion, a downstream end portion and an intermediate portion extending between the upstream end portion and the downstream end portion. The upstream end portion of the outflow cannula is connected to the pump casing such that blood is conveyed from the blood flow outlet of the pump casing into and through the intermediate portion of the outflow cannula towards the downstream end portion of the outflow cannula, wherein the downstream end portion has a blood flow outlet through which blood can exit the outflow cannula. At least a portion of the intermediate portion of the outflow cannula has an outer diameter that is larger than an outer diameter of the pump casing.
