Rotor for a fluid pump, and method and mold for manufacturing same

A rotor for a compressible blood pump wherein the compressible blood pump can be introduced into a patient through a blood vessel and into a patient's body, the rotor comprising:

• at least one impeller element for conveying blood, the at least one impeller element comprising a central plane,
• wherein the at least one impeller element is configured to be radially compressed and expanded between a compressed state and an expanded state, the at least one impeller element further comprising a plastic material reinforced by strand-like reinforcement elements, the strand-like reinforcement elements disposed on the central plane of the at least one impeller element;
• wherein the rotor is intended to rotate about an axis of rotation, and
• wherein the plastic material has a Shore hardness of <100 D,
• wherein, a rigidity of the strand-like reinforcement elements and the Shore hardness of the plastic material is selected such that when the at least one impeller element is radially compressed, a region of the at least one impeller element is bent and, in the bent region of the at least one impeller element, the strand-like reinforcement elements are deflected from the central plane.
