| description | A rotor for a pump, such as a blood pump, may include a hub configured to rotate around a central axis, and at least one rotor blade coupled to and extending away from an outer surface of the hub, the rotor blade comprising a medical-grade polyurethane, the rotor blade configured to have a crimped state and a running state. The medical-grade polyurethane may be configured for casting or injection molding, and upon curing, the medical-grade material advantageously has a shore A hardness of 90-100, or a shore B hardness of 35-55, and a Young's modulus of 60 MPa-250 MPa. When crimped, the rotor blades are compressed and exposed to strains of up to about 160% in a dry environment at temperatures of 20-25° C. When running, the rotor blades are expanded and exposed to strains of up to 10% in a wet environment at temperatures of 36-38° C. |
