Abstract: An in-vivo micro blood pump is disclosed. The pump, comprising: a holder configured to be inserted into a blood vessel to be anchored to the blood vessel by one or more stents; and two or more micro-impellers located inside the holder while having the same rotation axis. Each micro-impeller may include a rotor and a cylindrical stator. The rotor may include a first hollow cylinder; two or more internal blades, extending inward from a wall of the first hollow cylinder, wherein the radial dimension of each blade is less than an internal radius of the first hollow cylinder; and one or more magnets. The cylindrical stator may include one or more electromagnets. A first micro impeller has a first blade pitch, and a second micro impeller has a second blade pitch, different from the first blade pitch.
