The probe has insulated conductor wires respectively linked to distal and proximal electrodes of a probe head whose anchoring screw (24) is mobile inside a tubular exterior body of the head. Coupling units couple a deployment mechanism of the head to couple a mobile element (26) of the head to the body and have a helical guide carried by the element. The guide is mobile in translation and rotation inside the body and transforms a rotation movement on the body by rotation of a hollow sheath (12), into a movement of the element from a retracted position to a deployed position, and vice versa. |
