Abstract
The invention relates to a compressible and expandable blade for the rotor of a fluid pump having at least two lamellae which are disposed adjacently, are pivo table respectively relative to an axis of rotation 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.
Claims15
A compressible and expandable rotor for a fluid pump, the rotor comprising:
- a rotor shaft;
- and
- a plurality of lamellae,
- wherein each lamella has a first end and a second end and the first end of each lamella is independently pivotably mounted to the shaft,
- wherein, each lamella is pivotable relative to an axis of rotation of the rotor such that the rotor is compressible and expandable,
- wherein, when the rotor is in an expanded state, the plurality of lamellae form a continuous rotor blade.

A pump assembly comprising:
- a catheter;
- a compressible and expandable rotor disposed at a distal portion of the catheter, the rotor comprising:
- a rotor shaft;
- and
- a plurality of lamellae,
- wherein each lamella has a first end and a second end and the first end of each lamella is pivotably mounted to the shaft,
- wherein, each lamella is pivotable relative to an axis of rotation of the rotor such that the rotor is compressible and expandable,
- wherein, when the rotor is in an expanded state, the plurality of lamellae form a continuous rotor blade;
