An implantable cuff includes an elastic collar, at least one conductive segment disposed on or within the elastic collar, and at least one conductor in electrical communication with the at least one conductive segment. The elastic collar defines an internal opening configured to receive an internal body tissue. At least a portion of the elastic collar includes a stiffening region having a stiffness greater than a second region of the elastic collar. The at least one conductor is configured to operably mate with an apparatus capable of delivering electrical stimulation to, and/or recording an electrical activity of, the internal body tissue.
