a hub configured to rotate around a central axis; and
at least one rotor blade coupled to the hub and extending away from an outer surface of the hub, the at least one rotor blade comprising a medical-grade material, the at least one rotor blade configured to have a crimped state and a running state;
wherein the medical-grade material is configured for casting or injection molding, and upon curing, the medical-grade material having a shore A hardness value of 90-100 or shore B hardness value of 35-55 as determined using DIN ISO 7619-1 and a Young's modulus of 60 Mpa-250 MPa as determined used ISO 527;
