    • 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.
    • 本发明涉及一种用于可植入医疗装置的探针(10)。 探针具有远端(2)和近端(3),并且探针(10)还包括位于远端的电极(1)。 电极连接到从电极延伸到探针的近端的线(5),其中线的电阻率沿着线的长度是不均匀的。 导线在探头的远端可能具有高电阻率,而其他地方的电阻率较低。 高电阻率线降低植入装置的组织中的峰值电流密度,从而防止在MRI检查期间的组织的破坏性加热和/或不期望的刺激。 这高度有助于MR安全性,这是这些可植入电刺激装置的高度期望的特征。
