1. An intravascular blood pump for percutaneous insertion into a patient's blood vessel, comprising:
a catheter, and
a pumping device attached to the catheter, the catheter extending along a longitudinal axis and having a distal end and a proximal end opposite the distal end along the longitudinal axis, the catheter comprising an elongate stiffening structure fixed to the catheter, the stiffening structure extending continuously longitudinally along a length of the catheter between the proximal end and the distal end of the catheter,
wherein the stiffening structure has a minimum bending stiffness of about 0.00005 Nm2 to about 0.01 Nm2 and is not subject to plastic deformation if bent with a minimum bending radius 10 mm.
