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.
Claims14
A fluid pump comprising:
- a compressible rotor comprising:
- at least one blade;
- and
- a plurality of anisotropic cavities formed within the at least one blade, each anisotropic cavity having a greater extension in a first direction than in directions perpendicular to the first direction,
- wherein each of the plurality of anisotropic cavities abuts at least three other anisotropic cavities of the plurality of anisotropic cavities.
