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.
