A tagging device for marking the location of lesions within the body prior to a surgical procedure such as excision or biopsy. The device includes an elongated tube having one end supported on a housing and a second end extending distally therefrom. An anchor is positioned within the distal end of the elongated tube and has an elongated member extending proximally therefrom. An actuation assembly including a plunger is movable within the tube to engage and push the anchor from the distal end of the tube. The anchor and the actuation assembly are positioned and configured such that the anchor is pivoted from a position parallel to the longitudinal axis of the tube to a position perpendicular to the longitudinal axis of the tube as it as being pushed from the tube.

[ What is claimed is:] [14.] A tagging device for identifying a particular location within a mass of body tissue comprising: an elongated tube having a proximal end and a distal end; an anchor releasably positioned within the distal end of the elongated tube; an elongated member having a first end connected to a central portion of the anchor; and a plunger which defines a hollow tube slidably positioned within the elongated tube, a second end of the elongated member being positioned within the hollow tube, the plunger being operably engageable with the anchor to move the anchor from a first position within the elongated tube to a second position ejected from the elongated tube, the distal end of the hollow tube and of the elongated tube having a longitudinal slot dimensioned to permit passage of the elongated member during movement of the anchor between the first and second positions; and wherein the plunger and anchor are configured to rotate the anchor continuously as the anchor moves between the first and second positions.
