Abstract
This disclosure describes techniques for controlling a depth of propagation of a stimulation field extending from an outer diameter of a lead body of an implantable stimulation lead. An implantable electrical stimulation lead may include a lead body, and at least one electrode arranged as a ring. An outer diameter of the ring may be different than an outer diameter of the lead body. A ring with a diameter smaller than the diameter of the lead body may be useful in limiting the depth of propagation of the stimulation field within patient tissue. A ring with a diameter greater than the diameter of the lead body may be useful in extending the depth of propagation of the stimulation field.
