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： Several embodiments of a catheter are described, having a balloon configured to slowly inflate and then quickly deflate to create an area of low pressure in the vessels. The balloon can be cycled near the vessels of the kidneys, thereby helping to draw out blood from the kidneys and enhance fluid processing to the bladder.

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： 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.
