Abstract: An intravascular blood pump for percutaneous insertion into a patient’s vasculature comprises a pumping device and a supply catheter. The pumping device comprises a pump section with a blood flow inlet, blood flow outlet, and impeller for conveying blood from the inlet to the outlet and further comprises a drive section connected to the pump section and adapted to drive the impeller. The supply line supplies the drive section with electric energy for driving the impeller. The supply catheter supplies electric energy for driving the impeller. The pump section is axially arranged between the drive section and the supply line. The pump section includes a flexibly bendable cannula, and electric lines are arranged across the cannula in a manner to prevent their rupture in the event that the cannula is subject to bending.

The pumping device comprises a pump section with a blood flow inlet, blood flow outlet, and impeller for conveying blood from the inlet to the outlet and further comprises a drive section connected to the pump section and adapted to drive the impeller. The supply line supplies the drive section with electric energy for driving the impeller. An anchoring structure is provided at a distal end region of the intravascular blood pump. A connecting catheter may be attached to the anchoring structure from distally in order to guide the intravascular blood pump through the patient's vasculature in a distal direction.
