Abstract

The invention relates to a fluid pump comprising 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.
