Abstract
A localization device (10) comprising an outer needle cannula (11), an optional inner sleeve cannula (13) and an anchor stylet comprising a plurality of preformed superelastic alloy wires (12). Once the distal portions (14) of the wires (12) are deployed from the ends of the sleeve and needle cannulae, they function as curved barbs (15) projecting outward to anchor the device into tissue, an organ, or a foreign body. A slidable locking member (18), such as a pin vise, can be included over the outer needle cannula for securing the localization device against a template.
