SYSTEM FOR TERMINATING ABANDONED IMPLANTED LEADS TO MINIMIZE HEATING IN HIGH POWER ELECTROMAGNETIC FIELD ENVIRONMENTS
First Claim
1. A system for terminating an abandoned implanted lead to minimize heating in a high power electromagnetic field environment, comprising:
- an implanted abandoned lead having a proximal end and a distal end, and impedance characteristics at a selected RF frequency or frequency band;
an abandoned lead cap having an energy dissipating surface and associated with the proximal end of the implanted abandoned lead; and
an energy diversion circuit conductively coupling the implanted abandoned lead to the energy dissipating surface to facilitate transfer to the energy dissipating surface of high frequency energy induced on the implanted abandoned lead at the selected RF frequency or frequency band.

Abstract
An energy management system facilitates the transfer of high frequency energy coupled into an implanted abandoned lead at a selected RF frequency or frequency band, to an energy dissipating surface. This is accomplished by conductively coupling the implanted abandoned lead to the energy dissipating surface of an abandoned lead cap through an energy diversion circuit including one or more passive electronic network components whose impedance characteristics are at least partially tuned to the implanted abandoned lead'"'"'s impedance characteristics.
