摘要： Catheter blood pumps that include a collapsible blood conduit, a collapsible scaffold portion, and a taper formed in the collapsible scaffold. The collapsible blood conduit defines a blood lumen. The collapsible scaffold is adapted to provide radial support to the blood conduit. The blood pump also includes one or more impellers. In some embodiments, the one or more impellers can also include a taper. The taper of the blood conduit can match the taper of the one or more impellers.

摘要： Methods and devices for supporting circulation. The methods may include positioning a blood pump in the arterial vasculature or the venous vasculature. The methods may include positioning a pump portion of the blood pump in a descending aorta, an inferior vena cava, a renal artery, and/or a renal vein. The methods include delivering a pump portion of a blood pump to a target location and rotating one or more impellers to move blood through the pump portion.

摘要： Devices for moving blood within a patient, and methods of doing so. The devices can include a pump portion that includes an impeller and a housing around the impeller, as well as a fluid lumen. The impeller can be activated to cause rotation of the impeller and thereby move fluid within the fluid lumen.

摘要： Catheter blood pumps that include an expandable pump portion. The pump portions include a collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers. The pump portion may also include a blood mover that is adapted to move blood to reduce stagnation, and is separate from the impeller.
