Patent ID: 7986999

Claim:
A lead assembly for an implantable medical device, the lead assembly comprising: a lead body having a first portion and a second portion, the first portion adapted for coupling to a pulse generator and the second portion adapted for implantation in or near a heart; first and second co-radial conductive coils positioned within the lead body and electrically isolated from each other, wherein the first and second conductive coils include a first and second number of coil turns and the first number is substantially equivalent to the second number; at least one capacitor element connected in parallel with the first conductive coil and at least one capacitor element connected in parallel with the second conductive coil; first and second electrodes located at the second portion and respectively coupled to the first and second conductive coils; third and fourth co-radial conductive coils positioned within the lead body and electrically isolated from each other, wherein the third and fourth conductive coils include a third and fourth number of coil turns and the third number is substantially equivalent to the fourth number, and wherein the third and fourth co-radial coils are co-axial with the first and second co-radial coils; and third and fourth electrodes located at the second portion and respectively coupled to the third and fourth conductive coils.
