ABSTRACT:
A device for marking tissue locations is disclosed in which a localization wire comprises multiple strands twisted together. At predetermined spaced intervals along the length of the localization wire, the strands are twisted together more densely than along the remaining portion of the wire, providing readily identifiable markers which can be visualized under ultrasound or X-ray or can be felt by the physician's fingertips. The free forward end of each of the twisted strands is formed into a barb to anchor the forward end of the localization wire within the patient's tissues.
