    摘要： RF/MRI compatible leads include at least one conductor that turns back on itself at least twice in a lengthwise direction, and can turn back on itself at least twice at multiple locations along its length. The at least one electrical lead can be configured so that the lead heats local tissue less than about 10 degrees Celsius (typically about 5 degrees Celsius or less) or does not heat local tissue when a patient is exposed to target RF frequencies at a peak input SAR of at least about 4 W/kg and/or a whole body average SAR of at least about 2W/kg. Related devices and methods of fabricating leads are also described.

    摘要翻译： RF / MRI兼容的引线包括至少一个导体，其沿​​长度方向至少翻转两次，并且可以在其长度的多个位置处至少翻转两次。 至少一个电引线可以被配置成使得引线将局部组织加热到小于约10摄氏度（通常约5摄氏度或更低），或者当患者暴露于峰值输入处的目标RF频率时不加热局部组织 SAR至少约4W / kg和/或全身平均SAR至少约2W / kg。 还描述了制造引线的相关器件和方法。
