A kit for penetrating the cardiac septum and for the placement of a trans-septal device, in particular of a stimulation probe, in a left heart cavity. This kit includes a penetration guide ( 16 ), a handling stylet, a piercing stylet ( 38 ) and a guiding stylet ( 56 ). The penetration guide ( 16 ) comprises a probe body with a flexible hollow sheath ( 22 ) successively receiving these stylets, and a probe-head ( 18, 24 ) having an extendable helicoid screw ( 20 ) for anchoring to the wall of the septum ( 10 ). The piercing stylet ( 38 ) presents a sharp distal extremity ( 44 ) emerging from the frontal face, through the anchor ( 20 ), over a distance at least equal to the local thickness of the septum ( 10 ), so as to traverse through the septum. A guiding stylet will be then introduced into the sheath to form, after withdrawal of the penetration guide ( 16 ), an axial guide traversing the septum, for the introduction therethrough of a trans-septal device.
