1. An assembly for fitting/removing a propulsive heart pump (36) in a sleeve secured in an opening in a ventricular wall (33), said assembly comprising:
an assembly element of a pump body of the heart pump (36);
a guide element (30) with a distal end, a proximal end, and a lumen (31) extending between, and opening at, said distal and proximal ends; and
a gripping unit (37) configured to slide in said lumen (31), a free end of said gripping unit (37) comprising an assembly part which is complementary with said assembly element of the pump body,
said assembly part of said gripping unit (37) configured to cooperate with said assembly element to present two positions that include i) a locked position in which said gripping unit (37) is mechanically joined to the pump body wherein the gripping unit (37) grips the pump body in order to displace the heart pump (36), and ii) an unlocked position with respect to the pump body wherein said free end is separable from the pump body.
