| 摘要 |
This disclosure provides a medical lead assembly that includes a lead body having a proximal end configured to couple to an implantable medical device and a distal end. The lead assembly further includes an electrode assembly located at the distal end of the lead body, the electrode assembly including a tip electrode, a conductive electrode shaft that is electrically coupled to the tip electrode and an energy dissipating structure that is coupled to at least a portion of the conductive electrode shaft at high frequencies to redirect at least a portion of the current induced in the lead by a high frequency signal from the tip electrode to the energy dissipating structure. |
