摘要：
A marking device includes a handle defining a hollow interior, and a delivery assembly slidably mounted to the handle. The delivery assembly includes a cannula, a stylet assembly, an imaging marker, and an actuator. The cannula has a cannula distal end with a marker recess. The imaging marker is disposed within the marker recess. The actuator is operably coupled to the delivery assembly and is operable to transition the delivery assembly through at least three configurations: a first configuration characterized in that the cannula is positioned in an extended position and the stylet assembly is positioned in a ready position a second configuration characterized in that the cannula is positioned in the extended position and the stylet assembly is positioned in an implant position and a third configuration characterized in that the cannula is positioned in the retracted cannula position and the stylet is retracted into the handle.
