PERCUTANEOUSLY APPLIED BLOOD PUMP CAPABLE OF CHRONIC SUPPORT

原文（中国語）

A system and method for increasing cardiac output of a heart patient and/or diuresis is disclosed. The system can include a fluid pump with an expandable housing and an impeller. The impeller can be non-obstructive to at least some blood flowing between impeller blades of the impeller. The impeller can be housed in an expandable housing that is open to incoming flow which also reduces obstruction to blood flow. The fluid pump can be placed within and powered to rotate an impeller of the fluid pump in a first direction. The fluid pump can be switched to an unpowered state. In the unpowered state the impeller can be rotated by blood flowing through the fluid pump to reduce the obstructive effect of the impeller and/or to engage a power generating and/or physiologic conditions sensing mode.
