Radially compressible and expandable rotor for a pump having an impeller blade

A rotor for a blood pump, comprising:

• at least one impeller blade configured to rotate about a hub to convey a fluid, the at least one impeller blade having first and second sides oriented such that, when the blade rotates about the hub, the first side is a suction side and the second side is a pressure side, comprising:
• an impeller blade body,
• a first stiffening strut extending from a hub, the first stiffening strut having distal and proximal ends and a width and a length, the length extending from the distal end to the proximal end, the first stiffening strut being coupled to the hub at the proximal end, and
• a second stiffening strut coupled to the hub;
• wherein the at least one impeller blade is configured to be radially compressed from a first deployed state to a second compressed state, and wherein the first stiffening strut is deformable independently from the second stiffening strut during radial compression of the at least one impeller blade.
