Abstract
A lead assembly for an implantable medical device includes a lead body having a first portion adapted for coupling to a pulse generator and a second portion adapted for implantation. First and second co-radial conductive coils are electrically isolated from each other and include a first and second number of coil turns. The first and second number of coil turns include a number of matched turns and a number of unmatched turns, and the number of unmatched turns is less than approximately 2.0% of the total number of unmatched and matched turns. First and second electrodes located at the second portion are respectively coupled to the first and second conductive coils. At least one capacitor element is connected in parallel with one or both of the first and second conductive coils and/or between the first and second conductive coils.
