Abstract

Disclosed is a rotor for a compressible fluid pump, in particular a blood pump that can be introduced into a patient's body through a blood vessel; said rotor comprises one or more impeller elements, is compressible and expansible between an expanded state and a compressed state, is made at least in part of a fiber-reinforced plastic material, is provided for rotating about an axis of rotation, and is characterized in that in the expanded state of the rotor, a first percentage, i.e. more than 30%, in particular more than 50%, of the fibers runs substantially straight between the first end () thereof lying closest to the axis of rotation and a second end lying further away from the axis of rotation. According to the invention, the rotor retains its shape very well even when subjected to repeated mechanical stress.
