An implantable lead including a lead body including an outer surface, a proximal end, a distal end, and at least one electrode; an electrically insulating member that extends axially over a first portion of the outer surface of the lead body between the proximal end and distal end, the electrically insulating member defining at least one aperture that exposes a first portion of the at least one electrode when in a first position over the lead body; and a reinforcement member formed at least partially of a different material than the insulating member and coupled to the insulating member, the reinforcement member extending axially over the outer surface of the lead body between the insulating member and proximal end. The reinforcement member may be configured to transfer at least one of a radial or axial force from a proximal portion of the reinforcement member to the insulating member, wherein the at least one of radial or axial force transferred to the insulating member is sufficient to move the insulating member over the outer surface of the lead body. In some examples, the lead may further include a deployable lobe member configured to anchor the reinforcement member and insulating member adjacent a tissue site within a patient.
