10 Claims

1. A fluid pump, comprising a rotor with at least one rotor blade for conveying fluid, the rotor being variable with respect to its diameter between a compressed state, and an expanded state, wherein the at least one rotor blade deforms as the rotor transitions between the compressed state, and the expanded state, wherein the at least one rotor blade has a leading side and a trailing side with respect to a direction of rotation during conveying pump operation, and wherein the rotor is configured such that when the rotor is rotating during conveying pump operation, a fluid counterpressure is produced counter to the direction of rotation against the leading side of the at least one rotor blade, and wherein the leading side of the rotor blade comprises a first material and wherein the trailing side of the rotor blade comprises a second material, wherein the first material has a predetermined permanent elongation limit wherein the predetermined permanent elongation limit is produced by stretch-resistant fibers embedded in the first material.
