An implantable electrical lead comprising an elongate lead body comprising first and second ends and an outer housing defining an interior channel. At least one electrical contact is positioned along the elongate lead body. An anchoring system is disposed at one end of the elongate lead body. The anchoring system is movable between an elongate configuration and a compressed configuration. The compressed configuration has a greater diameter than the elongate configuration. A linkage is provided having a first end attached to the anchoring system, an intermediate portion disposed within the interior channel of the elongate lead body, and a second end disposed outside of the elongate lead body adjacent to the second end of the elongate lead body. Movement of the linkage away from the elongate lead body moves the anchoring system from the elongate configuration to the compressed configuration.
