Frequency selective passive component networks for implantable leads of active implantable medical devices utilizing an energy dissipating surface

A passive component network for an implantable lead of an active implantable medical device (AIMD), comprising:

• at least one leadwire having a length extending between and to a proximal end and a tissue-stimulating or biological-sensing electrode at a distal end;
• an energy dissipating surface disposed adjacent to tissue or within the blood or lymph flow of a patient at a point distant from the electrode;
• and
• a diversion circuit associated with the leadwire, for selectively diverting high-frequency energy away from the electrode to said energy dissipating surface for dissipation of said high-frequency energy as heat, said diversion circuit comprising at least one series resonant L-C trap filter.
