摘要：
Magnetically coupled reverse flow heart pump. The invention relates to an intraventricular pump comprising - a fixed casing (13, 14) with an upper part (13) forming a chamber for propelling the fluid towards the upper end, and a lower part (14) forming a stator and fixedly connected to the upper part, - at least one lateral opening between the upper part and the lower part, and forming an inlet chamber (16) of the fluid from the outside to the propulsion chamber, - an engine block formed by: - said stator (14) in which are arranged first magnetic elements (22), - a rotor (21) in the form of a bell at least partially covering the head of the stator and comprising second magnetic elements intended for magnetic coupling with the first magnetic elements of the stator, the bell having at least one opening (27) on its upper part so as to create a reverse flow (28) of the fluid from the inlet chamber (16) to the base of the stator via a passage (29) between the rotor and the stator, - a transmission shaft (20) comprising at least one link arm (24) making it possible to maintain the bell above the stator, the axis of the transmission shaft being superimposed with the axis of rotation of the bell.
