The probe (1) has electrodes (20) arranged near a distal end of a tubular body, and brought in contact with a region e.g. ventromedial hypothalamus (HVM), to be stimulated inside a body of a patient. A rigid stylet is introduced inside a slot of the tubular body, which has a non-rectilinear balanced shape different from that of the stylet. The tubular body having a progressive elbow (15) is flexible and elastic for configuring the stylet by deforming the tubular body in a reversible manner when the stylet is introduced in the slot.
