The electrode lead is provided with a tine assembly having tines which can be actively moved back and forth between a retracted position and an extended position. The tines are mounted on an electrode tip which is movable relative to an elongated tubular body and are fixed to the body so that upon movement of the tip relative to the body, the tines can be moved between the retracted and extended positions. A threaded rod which is rotatably mounted within the elongated body is used to move the conductive electrode tip relative to the non-conductive tubular body.
