Abstract:
The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.

Claim (Index 29):
A percutaneous pump, comprising:\n an expandable and compressible housing having a first inner diameter when compressed and a second inner diameter when expanded; a rotor disposed within the housing, the rotor having a compressed state, a first expanded state, and a second expanded state; the rotor comprising:\n a hub; and \n a helical rotor blade coupled to the hub and configured to convey fluid, wherein the helical rotor blade spans at least 180 degrees about the hub; \n wherein the helical rotor blade is configured to increase in diameter between the compressed state and the first expanded state, and to further increase in diameter between the first expanded state and the second expanded state to an expanded diameter, said increase in diameter from the first expanded state due at least in part to fluid counterpressure on the helical rotor blade; wherein the helical rotor blade is configured to increase in diameter from the compressed state to the first expanded state due at least in part to expansion of the housing from the first inner diameter to the second inner diameter.
