19 Claims

1. A fluid pump comprising:

at least one helical impeller blade that is rotatable about the axis of rotation; and

a tubular sleeve support device that houses the at least one helical impeller blade and is connected to an outer margin of the at least one helical impeller blade, the tubular sleeve support device is configured to pull the outer margin of the at least one helical impeller blade radially outwardly from the axis of rotation to transition the at least one helical impeller blade from a compressed state to an expanded state.
