Blood pump is implanted in vascular system, such as in pulmonary artery. The pump can project through native valve, such as pulmonary valve. In use, the pump substitutes in native valve on the contrary with retrograde flow. Pump can be axial-flow pump with tube-like envelope be adapted to fit in close to the bifurcated of the pulmonary artery space simultaneously project only be slightly moved closer to fibrous ring Pulmonary autograft.
