Motivation: Electrically short fragmented leads are sometimes left behind in the human body after the extraction of an active implantable medical device (AIMD). When a new AIMD is implanted near the fragmented leads, the radiofrequency (RF)-induced heating of the newly implanted AIMD could be altered.
Goal(s): Develop a method to evaluate the RF-induced heating of AIMD with fragmented leads in the vicinity.
Approach: We propose to use the electric field distribution which includes the presence of the fragmented leads with the AIMD transfer function model for RF-induced heating evaluation.
Results: The proposed method can effectively predict the RF-induced heating for AIMDs near fragmented leads.
Impact: It was observed that the RF-induced heating for AIMD system can be altered by the nearby fragmented leads.
