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 pivotable 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.
Claims23
A compressible and expandable rotor for a fluid pump, the rotor comprising:
- a plurality of individual rotor segments, each individual rotor segment including a hub segment and at least one lamella extending from the hub segment,
- wherein each hub segment is attachable to at least one axially adjacent hub segment such that the hub segments of the plurality of individual rotor segments form a rotor shaft and, when the rotor is in an expanded state, the lamellae of the plurality of individual rotor segments 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 plurality of individual rotor segments, each individual rotor segment including a hub segment and at least one lamella extending from the hub segment, wherein each hub segment is attachable to at least one axially adjacent hub segment such that the hub segments of the plurality of individual rotor segments form a rotor shaft and, when the rotor is in an expanded state, the lamellae of the plurality of individual rotor segments form a continuous rotor blade;
- and
- a compressible and expandable pump housing surrounding the rotor.
