Numerical Analysis of AIMD Lead Tolerances Using the Lead Electromagnetic Model

Influence of lead tolerances on the RF-induced power deposition (P) near a lead electrode was analyzed using the lead electromagnetic model and two sets of incident electric fields (E tan ) with different profiles. Our results indicate that tolerance analysis shall be done for all lead lengths and clinically relevant E tan because the sensitivity of P to a given variation of the lead properties can differ by an order of magnitude.
