Abstract
A therapy delivery element adapted to be implanted into a living body. The therapy delivery element includes an electrode portion with a plurality of electrodes. At least one elongated lead body is attached to the electrode portion. The elongated lead body includes a stylet coil having a stylet coil lumen. The stylet coil extends within the elongated lead body and along at least a portion of the electrode portion. A conductor assembly with a plurality of insulated electrical conductors is braided to extending around the stylet coil and to electrically couple to one or more of the electrodes. The conductor assembly includes an inner lumen with a diameter greater than an outside diameter of the stylet coil. Axial elongation of the elongated lead body reduces the inner diameter of the conductor assembly. A low durometer insulator extends around the conductor assembly. A stylet sized to slide freely within the stylet coil lumen is provided for use during implantation of the therapy delivery element into the living body.
