Abstract
The invention relates to a fluid pump having at least one impeller blade (1, 1′, 1″) which is rotatable about an axis of rotation (3) and conveys a fluid in operation and comprising a support device (4, 6, 7, 8, 9, 10, 12, 12′, 13, 13′, 14, 14′, 15, 17) which supports the at least one impeller blade (1, 1′, 1″) in at least one support region, wherein the support device is changeable between a first state in which the rotor is radially compressed and a second state in which the rotor is radially expanded; and wherein at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation (3) from the support region/support regions in the radially expanded state of the rotor.

1-15. (canceled)
A fluid pump comprising:
- a rotor, the rotor having a first end and a second end and comprising at least one impeller blade rotatable about an axis of rotation and configured to convey a liquid in operation;
- a tubular support device coupled to first and second shaft journals via one or more braces, wherein the one or more shaft journals are each aligned with the axis of rotation of the rotor, wherein the first shaft journal is positioned at the first end of the rotor and the second shaft journal is positioned at the second end of the rotor;
- and
- wherein the tubular support device houses the at least one impeller blade and the at least one impeller blade is supported by the tubular support device.
