Abstract
The invention relates to a rotor for a fluid pump, in particular for use in the medical sphere, the rotor being compressible for bringing to the place of use and thereafter being expandable. The compressibility is assisted by the provision of cavities, in particular also production of the rotor at least partially from a foam.
Claims16
A compressible rotor for an intravascular fluid pump comprising:
- at least one blade;
- and
- a plurality of deformable cavities disposed within the at least one blade which are filled or can be filled with a fluid, wherein at least a part of the plurality of deformable cavities is surrounded by an impermeable material of the rotor and is in fluid communication with at least another part of the plurality of deformable cavities or with the exterior of the rotor;
- and wherein at least one of the plurality of deformable cavities is oriented with a longitudinal axis perpendicular to an outer surface of the at least one blade;
- and
- wherein the rotor is comprised of foam.
