A site marker deployment device includes a housing defining a first portion, an outer cannula at least partially interposed within the first portion and having a proximal end and a distal end defined by an outer cannula aperture, an inner member at least partially interposed within the outer cannula, a first biasing portion, a second biasing portion, wherein the second biasing portion will selectively urge the outer cannula to move proximally relative to the inner member, and a site marker selectively disposed within the outer cannula adjacent the inner member, near the distal end of the outer cannula. The first biasing portion will selectively urge a site marker at least partially within the outer cannula.
