    摘要: The invention relates to a probe (10) for an implantable medical device. The probe has a distal end (2) and a proximal end (3), and the probe (10) moreover comprises an electrode (1) at the distal end. The electrode is connected to a wire (5) extending from the electrode to the proximal end of the probe, where the resistivity of the wire is non-uniform along the length of the wire. The wire may have high resistivity at the distal end of the probe and low resistivity wires elsewhere. The high resistivity wires reduce the peak current density in the tissue of an implanted device, and thus prevents destructive heating and/or undesired stimulation of tissue during MRI examination. This highly contributes to MR safety which is a highly desired feature for these implantable electrical stimulation devices.

    摘要: 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.
