A lead includes a lead body defining a lumen extending through the lead body; a conductor disposed in the lumen; a slit extending from an exterior of the lead body through at least a portion of the lead body to the lumen; and a contact strip. A portion of the contact strip is optionally disposed in the slit and is in contact with a portion of the conductor. A second portion of the contact strip is optionally wrapped around the lead body. A method of making a lead includes disposing one or more conductors in a lumen of a lead body; forming a slit from an exterior of the lead body to the lumen to access a portion of at least one conductor disposed in the lumen; coupling a flat contact strip to the portion of the conductor, and wrapping the contact strip around the lead body.
