A system includes an introducer sheath having a sheath wall and a longitudinal axis, an electrode lead including a lead body and at least one electrode at a distal end of the lead body. The distal end of the lead body is received within the sheath. At least one anchor wire is within the sheath and has a proximal end attached to the distal end of the lead body. The a least one anchor wire moves through at least one opening in the sheath wall responsive to movement of the lead body relative to the introducer sheath.
