We present a method to analyze the RF induced tissue heating at the lead tip of medical implants. This is done by applying the theory of field-to-transmission line interaction to a single insulated wire embedded in a tissue-like medium. A comparison of calculations with FDTD simulations was done. With our approach it is possible to analyze the effect of characteristic transmission line impedance, wire bending and/or electric field configuration on the current distribution of conducting leads.
