Abstract

An apparatus for percutaneously implanting a localization wire into a tissue mass includes a handle having a grip portion and a base. The grip portion is slidably mounted to the base. The base has a keyway. A cannula is movable relative to the handle between an insertion position and a retracted position. A localization wire is positioned to extend from the handle and into the cannula lumen. An actuator is coupled to the cannula and is configured to operate between a charged condition and a discharged condition to retract the cannula. A collar is mounted to the cannula. The collar includes a key having a key projection. The key projection is not aligned with the keyway when the actuator is in the charged condition and the key projection is aligned with the keyway to facilitate retraction of the cannula toward the retracted position to effect the discharged condition.
