A pump designed for the circulation of a fluid. The pump includes a casing and a turbine arranged in the casing and designed to perform rotational movements relative to the housing. The turbine has a body designed to perform rotational movements and a hollow central portion, through the body from side to side and intended for the passage of fluid through the turbine. The turbine also comprises at least one blade disposed on the wall internal body, in the hollow central part, and designed to circulate the fluid. The pump can be implanted into the ventricle of a heart so as to increase blood flow. The architecture of the pump is characterized by a reduced weight, which improves patient comfort, reduces consumption pump motor motor and reduces stress on the cells blood.Pompe cardiaque équipée d'une turbine à pales internes.L'invention concerne une pompe conçue pour la circulation d'unfluide, cette pompe comprenant un carter (9) et une turbine (1) disposéedans le carter et conçue pour effectuer des mouvements de rotationrelativement au carter. Selon l'invention, la turbine comporte :- un corps (2, 8, 81, 82) conçu pour effectuer des mouvements derotation,- une partie centrale creuse (8a, 81a, 82a), traversant le corps depart en part et destinée au passage du fluide à travers la turbine, et- au moins une pale (4, 5, 6, 7) disposée sur la paroi interne (3) ducorps, dans la partie centrale creuse, et conçue pour faire circuler lefluide.
