Abstract
The invention relates to a compressible and expandable blade (2) for the rotor of a fluid pump (30) having at least two lamellae (3, 4, 5) which are disposed adjacently, are pivo table respectively relative to an axis of rotation (Ia) of the rotor and moveable relative to each other, and abut against each other in the expanded state of the blade such that they form together a continuous blade surface.
Claims20
A rotor for a percutaneous blood pump, the rotor comprising:
- a rotor hub having a first end and a second end;
- a rotor shaft extending into the first end of the rotor hub, the rotor shaft configured to rotate the rotor hub about an axis;
- and
- a compressible and expandable continuous helical blade mounted to the rotor hub, the continuous helical blade having a pitch that increases along the continuous helical blade in a direction from the second end of the rotor hub to the first end of the rotor hub.
