[ 18. An intravascular rotary blood pump, comprising:
a catheter (10),
a pumping device (50) disposed distally of the catheter (10) and having at its distal end a flexurally flexible flow cannula (53) through which blood is either sucked or discharged by the pumping device (50) during operation of the blood pump, and
at least one pressure sensor (27, 28A, 30) having at least one optical fiber (28A) fixed along a neutral fiber of the flow cannula (53) selected to prevent breakage of the fiber (28A) during bending of the flow cannula (53) while the blood pump is guided through a vascular system of a patient, wherein the neutral fiber of the flow cannula (53) is formed by locally strengthening the flow cannula. ]
