Implantable medical leads having resistance characteristics adapted to dissipate radio frequency (RF) electromagnetic energy during medical procedures such as magnetic resonance imaging (MRI) are disclosed. An illustrative medical device includes a lead having an inner electrical conductor operatively coupled to an electrode and a pulse generator, and one or more outer resistive shields that radially surround the inner conductor and dissipate RF energy into the surrounding body tissue along the length of the lead.磁気共鳴撮像(MRI)などの医療処置中に無線(RF)電磁エネルギーを消散させるようになっている抵抗特性を有する埋め込み型医療リード線。例証的な医療デバイスは、リード線を含み、リード線は、電極およびパルス発生器に動作可能に結合された内側電気導体、ならびに、内側導体を放射状に囲み、リード線の長さに沿う周囲の身体組織内にRFエネルギーを消散させる1つまたは複数の外側抵抗性シールドを含む。
