Abstract

A fluid pump includes a rotor with at least one rotatable impeller blade, the rotor having a compressed state and an expanded state, and a support device coupled to an outer radial edge of the at least one impeller blade. The support device is changeable between a first state in which the support device is radially compressed associated with the compressed state of the rotor, and a second state in which the support device is radially expanded associated with the expanded state of the rotor. In the expanded state of the rotor, the at least one impeller blade extends at least partly radially inward from the support device. The support device is a ring that at least partly surrounds the at least one impeller blade, the ring having a longitudinal axis parallel to an axis of rotation of the rotor.

Claims21

Dependent claims

A fluid pump comprising:

a rotor, the rotor comprising at least one impeller blade rotatable about an axis of rotation and configured to convey a fluid in operation, the rotor having a compressed state and an expanded state;
and
a support device coupled to the at least one impeller blade at an outer radial edge of the at least one impeller blade, wherein the support device is changeable between a first state in which the support device is radially compressed associated with the compressed state of the rotor and a second state in which the support device is radially expanded associated with the expanded state of the rotor;
and
wherein the at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation from the support device in the radially expanded state of the rotor, and wherein the support device is configured as a ring at least partly surrounding the at least one impeller blade, a longitudinal axis of the ring parallel to the axis of rotation.
