Abstract

The invention relates to a probe for an implantable electro-stimulation device. The probe (20) has a distal end (12) and a proximal end (13), and moreover comprises: one or more electrodes (11) a shield (21) of conducting material covering a major part of the probe, said shield extending from the vicinity of at least one of the one or more electrodes (11) towards the proximal end (13) or towards the distal end (12) of the probe (20); and a layer (22a, 22b) of insulating material covering part of the shield (21) in the vicinity of the at least one of the one or more electrodes. The shield protects wires (14), extending from electrodes to the proximal end of the probe, from undesired interference of external RF fields. The exposed part of the shield not covered by the layer of insulating material serves as a return electrode for the electrostimulation signal path.
